NOTE BY GPSPASSION 20090624 - 3:00 PM PST : Garmin have just made the v3.60 software available via the WebUpdater to fix this "dead GPS" problem. This will only help those who can still power on their 7x5 GPS, others will have to send it in to Garmin with a quoted 15 day turnaround. As a side note some revived their unit by opening it following this YouTube video and disconnecting the battery for 30 seconds, but be advised that this is a risky operation that requires a Torx 5 screwdriver and voids the warranty.

NOTE BY GPSPASSION 20090623 - 7:15 AM PST : Late last night we started getting reports in the forums that Garmin nuvi 765 systems were failing (and now 755s too). The scenario being : a pop-up saying a GPS update was being rolled out and then the nuvi powering off and refusing to power on again !

It is not known at this point what might be causing this, but the recent and temporary failure of the Omnitech GPS and acknowledgment by Rockwell Collins that there is a bug in some GPS receivers they built that would cause a date problem after June 20th 2009, could indicate that a scheduled fix for the 765's MTK GPS Chipset went wrong...Garmin are asking people to RMA their dead units so there is apparently no easy fix, but in case you own a 765 that hasn't gone bad, you can try renaming the GPS update files as this has spared SergZak's 765 it seems


All was fine with my 765T until today. While driving home from work all of a sudden I get a pop up about some GPS update. For the next five minutes the display alternates between acquiring satellites and GPS update. I thought cool another update. Then the Nuvi just died. I cannot power it on anymore either in the mount or from my PC. Well long story short I called tech support and got an RMA. Bummer

Using WebUpdater I downloaded new soft for my garmin 760, after download was completed I disconnect my Garmin 760 from computer and it started soft installer as usually, and at the same time It completely shutdown it self, might be because of the battery went dead. But after trying to charge it nothing happened, garmin stay completely dead, can't even turn it on. Tried to connect to computer via USB but no sights of any life at all? Tried to disconnect from main battery, wait and connect again and nothing changed. Any Help would be appreciated. Thanks
NanaimoRick Posted - 08 févr. 2010 : 17:50:41
Possible that the battery has become completely run down. When is happens it is often difficult to get the Nuvi to start up. Have you attached it to the traffic cable for your vehicle and started the vehicle engine up? This will often get the unit up and running again. Leave it for a few minutes to get some power in the battery and then try the AC adapter or USB cable again.

-> New v3.80 software for Garmin nuvi 7x5
pratzert Posted - 31 août 2009 : 15:01:24
My 775t has Software V 3.60 and GPS Software V 2.90.

I tried running WebUpdater several times and it keep ssaying I already have the latest installed.

So, what the heck is v 3.80, where did it come from and what are the changes from v 3.60 ?
pin13689 Posted - 17 août 2009 : 12:37:27
bought 2.5 weeks ago a 765T and was never working properly (screen calibration way off when connected to 12V, no tmc ....), last wednesday went to Garmin Brussels, they saw the problems and i got a new unit with software version 3.80. the guys at brussels neither did know of the new software, they were going to ask some explanation to garmin uk

anyway, mine is working now as it should (finally ...)
Toby737 Posted - 17 août 2009 : 11:52:36
I went to the Garmin Service Centre today and told the guy there that the nuvi has died.

He went away and then came back and gave me a replacement unit. When I switched it on and inspected the software version, it said 3.80.

So I guess they might be releasing EU FW 3.80 some time soon.
Toby737 Posted - 15 août 2009 : 09:56:41
Hi all,
Tried numerous things...
He did try leaving the nuvi on charge for the entire night. I lent him my Garmin wall charger. No joy.

So he approved for me to open up his nuvi to unplug the battery for > 30 secs then plug back in again, still no joy.

Even had it plugged in to the wall charger with battery unplugged, no luck.

Looks like it's going back to Garmin. Hopefully they won't be able to tell that the unit has since been opened.

Just strange that it was all updated to 3.6 and all other updates done via WebUpdater and just recently died like those described with FW 3.4.
jonstrong Posted - 14 août 2009 : 17:24:30
@Toby -

I'm wondering if the battery is dead? Have you tried leaving it plugged into the USB cable on a powered-up PC overnight, and then attempt to turn it on again? As Rick suggested, it seems the software satisfied the problems of the folks on this forum who had been reporting issues, so it's pretty unlikely that the software is still an issue. If not the battery, then there's a good possibility that there's another issue lurking within...
NanaimoRick Posted - 14 août 2009 : 15:33:45
IMHO since there hasn't been a post in this thread for 3+ weeks, the latest firmware update more than likely fixed the problems reported here. Of course another possibility is that your mates issue is something completely unrelated.
Toby737 Posted - 14 août 2009 : 12:52:37
I had a mate who purchased a new 765 a couple of weeks ago and ensured that all the latest updates were applied to his 765, anyway just today, the unit didn't budge from Aquiring Satellites for some time, then the unit just shut itself down.

Now the unit won't power up at all. So maybe it can happen to units with 3.6 firmware?
mmaslar Posted - 22 juil. 2009 : 15:35:51
There may be some small updates to the cities that already have pretty detailed 3D maps, but I know that in Atlanta, not all of the buildings are on the maps, so I'm hoping they add some more with the next update.
Chazz8 Posted - 21 juil. 2009 : 22:33:29
I was not thinking of 3d building in MapSource either. But now you have me thinking that there are probably no updates to the big cities where the 3d buildings are. Sorry to go off topic.
mmaslar Posted - 21 juil. 2009 : 21:26:59
Not sure about mapsource. My 755T has 3D buildings, but the last map update was in April, so no new buildings since then. I would expect another update to come around the end of this month.
Chazz8 Posted - 21 juil. 2009 : 21:18:56
Thanks for the input regarding speed limit showing (or not) mmaslar. I was thinking like you to wait until the next map update. I just activated my one free map update via MyGarmin. I paid the $10 to have them send me a DVD so I can keep my MapSource updated too. I'm assuming that it come with an updated 3d buildings map too?
mmaslar Posted - 21 juil. 2009 : 13:46:09
I have not noticed a difference in the speed limits around Atlanta, and the traffic seems to be working here too. I was sent a new unit, but they told me to keep all of my peripherals, so the traffic receiver is the same as my original. All of the speed limits are showing up as they have in the past, even the ones that were wrong are still wrong. The speed limit data is built in to the maps, which Garmin receives from Navteq, so I'm not sure if the speed limit problems are something software related or not. I would assume that if any of them are showing up, then your unit is displaying them properly. My guess is that if it was software related, it would be all or nothing. Since some are showing up, and others not, I would wait until the next map update to see if any new ones start showing up.
Chazz8 Posted - 21 juil. 2009 : 04:11:53
Here is how the end of my 755t repair saga went...

My Nuvi 755t was permanently off, and since it was less than 10 days old when I sent it in (I did not want to take it apart), they emailed me a prepaid US Postal Service label and promised a brand new Nuvi. They suggested that I return it where I bought it, but I got the last one they had and at %25 off. Following their instructions I sent back the original box with everything that came with the nuvi with a note on top re-stating that they were going to send me a new nuvi with everything. Just under two weeks later I got back a small box with my original nuvi with stickers on the back AND NOTHING ELSE. So I called Garmin support and got right through (yeah). They were very apologetic and explained that after my unit was sent in, somebody made the decision to repair&update and send back all the Nuvi's that just needed the battery disconnect/reconnect. I tried to get them to honor their original offer and send me a new 755t, but it was a firm NO. They were already committed to sending new peripherals, but I thought that 3 strikes (changed original offer, did not communicate change in plan, forgot to send back peripherals, and I miss my Gamin 755t retail box (still have my 350 box)) warranted whatever I wished for. During our discussion I'm starting to get frustrated, so I ask him what he can do to make up for the hat trick cluster muck. He suggests a free new faux leather case that opens like a wallet and has a cut out for access to the touch screen. I could have sworn that he agreed with me that it could stay in the case and connect to the cradle, but that is a no go. That made me feel better, and he said it would all be sent 2nd day. Each peripheral came back in new Garmin clamshell plastic, except for the GTM 20 traffic receiver which came in bubble wrap label recently reconditioned and different that the one I returned. I sent the "old" traffic receiver with the led lights built into the plug that goes into the 12v socket and got the new cable with the rectangle perturbation near the plug that goes into the cradle. SergZak says “From what I have heard from other users/forums, the newer GTM 20 (receiver in-line on the power cord) seems to be less sensitive that the original unit.” I’m not used to traffic, and I don’t think I get much (free) traffic info here around Syracuse NY, so I’m not too bummed about that.

Now on to my review of my repaired 755t with UnitSW 4.6:

Came back with favorites intact.

Acquires sats fast as usual. I believe HotFix still working. I asked Garmin support during conversation above and he said that he sits near Garmin automotive and he had not heard of anything wrong with HotFix (around the time of 7x5t problems)

I’m not seeing speed limits very much at all anymore. I even did a master reset to see if that helped. With the old UnitSw I marveled at how I had to hunt for a road that did not show speed limits. Now I have to hunt for a road that will show speed limits. I look forward to comments regarding the speed limits so I know if I should call Garmin support and try for that new 755t again.

I don’t detect any changes with street names labels since the repair and UnitSW update. I have noticed on the old UnitSW and 4.60 that if you want more street names to show on the map all you have to do is zoom in. My Nuvi 750 shows more street name labels than the 755t, but that is a small price to pay for the quicker screen refresh on the 755t.

Hidden Log screen still works.

I have not lost sats in 20 hours of use. I did have one reboot the first day back while I was in the traffic menu (GMT Status) accessible by pressing the speedometer.
mmaslar Posted - 20 juil. 2009 : 22:04:35
I just got mine back a few days ago. I had to pay to ship it to them, but they shipped it back overnight. I think it cost me $7 to ship it priority mail to Garmin. They sent me a whole new unit back, so after I got the new unit, I had to call and get my registration and lifetime maps switched to the new unit since the serial numbers were different. The new one works like a charm.
gpspassion Posted - 20 juil. 2009 : 22:01:32
Welcome to the forums and you certainly did save a good chunk of change !

Any news from those who sent their 765's back for repair, are they back with free shipping to and back from Garmin ?
kay Posted - 20 juil. 2009 : 19:13:34
Thank you for this info. I was able to repair my device by disconnecting the battery for 30 secs. My device is still under warranty, but due to my location Garmin refuses to pay my shipping costs to repair/ replace my device even though my device is just 2 months old and it is their faulty firmware. They didn't even contact me by my registered email about the issue when they posted the mandatory update, so i didn't find out about it only AFTER my device went dead!

But thanks to this forums, i am saved $175 US dollars to ship my device to Garmin or alternatively pay thieving Authorized Garmin Distributors $105 US dollars to repair it!

Not Good Enough GARMIN!

Good Work GPSPASSION and Vonhash!
mmaslar Posted - 06 juil. 2009 : 15:45:59
I just got off the phone with a Garmin rep, and they told me that the reason my unit was waiting for a replacement was because the repair order was set up before they were aware of the problem these units were having, so she said she will try to get it repaired instead of replaced and offered to upgrade the shipping to overnight since there has been such a delay. Hopefully, I get mine back soon.

Maybe Garmin connected it to a GTM 20 after the repair to test...



No it was not connected to the Receiver.......Doh!
I went out for a quick drive and hooked everything up and .....Voila! MSN Direct is back!....... the unit seems to be functioning perfectly.
BTW I did not loose any POI's or favorites thay are all still there!

Thanks SergZak And IsLNdbOi

Further Update on My Nuvi 785t that Died late last week. I sent it back Sat and need it back by the 9th for a vaction trip

Update:
Surprising turnaround time from Garmin. I received my Nuvi 785t back from the dead today and it is my original unit. It seems to work fine, but there is no MSN Direct Icon in the menus.
Has anyone else had this problem?

If so I would appreciate some help.
Thanks!
WmLane Posted - 03 juil. 2009 : 14:52:15
Garmin's turnaround, from what I've read on this and other forums as well as my own experience, has been quite good. Part of it might be that they realize it's a holiday weekend here in the U.S. I give them a lot of credit. And yes, UPS is delivering today (July 3).
synomenon Posted - 03 juil. 2009 : 02:50:49
Got my tracking number from Garmin. Shipped back to me via UPS ground and is supposed to be delivered to me tomorrow (the 3rd of July). I hope UPS is delivering tomorrow.
snj1013 Posted - 03 juil. 2009 : 02:46:09
I sent my 755T back to Garmin last week. They received it on Monday and I received it back tonight fixed. I live in Houston and it was sent back UPS Ground. Pretty good turnaround from Garmin!!!!
mmaslar Posted - 02 juil. 2009 : 21:36:46
hmmm... Maybe it's just the 755s that need to be replaced?

This is very interesting. I shipped my 765t back last Wednesday and got it back today. It's the same unit, which I'm glad. And though the CSR told me that all my favorites would be gone, they are in fact all still on my unit. Yea!

IsLNdbOi,

Performed the Hard Reset last night and took the 755T for a spin.
It seems working just fine now...


Thanks Boss !!!


Hogster Posted - 02 juil. 2009 : 13:08:11
I was expecting it to enter Mass Storage mode too ... the details escape me whether it was the Loading Maps screen or the Data Storange screen that was presented ... it might have been the latter actually. Agreed though, I'm surprised something bad didn't happen during the F/W update ... although as far as I understand, the updating part involving the computer is merely the copying of the files to the nuvi - when it goes through the boot-up process it actually does the upgrading, so perhaps it didn't have a chance to boot up to the point where the firmware would be updated ....

Well, strange occurrences aside, it's running on 3.60 at the moment with no problems fortunately!


David
peking97 Posted - 02 juil. 2009 : 13:01:47
When you connected it to the PC it should have started in Mass Storage mode not *Loading Maps* mode? Also given that it died (twice) in the middle of a F/W update I'd say your one lucky guy that it isn't a brick!

I had my unit refunded in full. I was told that all stock in the store had been recalled to have the firmware updated.

what firmware did your new unit come with?

The leaflet from Garmin described that all Nuvi 7x5s were affected and that old stock prior to 3.50 was affected so it seems they knew something was up and that's how they were able to have a fix issued so quickly.

Hi BAV,

So I got the new unit from Halfords (great!! )! The guy there said it was old stock from the Wandsworth warehouse which had been upgraded to the latest version of firmware .... So, I got it home and connected it to the computer ... firstly it got stuck in a loop where it started up, said loading maps, then restarted itself! I fiddled with the on/off switch a few times and managed to get it to connect to the computer ... To my surprise, the firmware version was 3.30! I installed the latest version, but when the unit restarted itself, the battery cut out before it could fully restart .... This happened twice, then I just left the unit attached as a USB mass storage device for a few hours to charge .... did the 3.60 update again and this time it rebooted successfully and has been working fine since!

So despite Halfords claim that the firmware had been upgraded, it hadn't! I also learnt from the guy who served me, that several days BEFORE the 23/6 meltdown (or whatever you want to call it ), Halfords was told to remove all their 765s from the shelves! So obviously Garmin knew something would happen but they didn't let the customers know about it ....

Hmmm well I won't go there ..... I'm just happy that I've got a brand new working unit with the latest version of firmware .... AND BLUETOOTH!

Cheers

I'm a new member and wanted to say how helpful these posts have been. I ordered a 765T from Amazon about a week ago, and after receiving it yesterday, immediately upgraded the software, and avoided a big hassle. Took it on a trip today and everything I tried seems to be working normally.

I note today that the unit is not listed or showing on Amazon.

I just talked to a Garmin Rep about my dead 785t which was actually shipped out on Monday.
FedEx shows the unit at their facility now. She confirmed that fact but said it takes up to 48 hrs to log them in before they hit the floor for repairs.........Ouch!
She also told me that the unit will be repaired, not replaced as some people in the forums are saying.
She did authorize overnite shipping back once the repair is done and put a note in the system to expidite ASAP. she also said she believes that Garmin is working weekends (overtime) to try and expidite these units.

We shall see! Right now it doesn't look good for getting it back by July 9th.
I may have to use those old reliable paper maps on vacation........ How quaint!

My NUVI 755T also started to get creepy on me last week. Suddenly, it can't acquire satellite signals. Then thanks to this thread, I read about the Firmware Update (Version 3.60) through the Garmin website to correct this issue. I did the update but now my 755T takes a good 10-15 minutes to lock in and acquire satellite signal. After turning it on, it'll show Acquiring Satellite for about 15 min and then it's fine after that. It does that every time I turn it on. Like I stated, it works fine after 10 min or so.... I just never had it this slow before. Anyone else encountering this slow satellite acquisition after the firmware update?

Thanks...
synomenon Posted - 01 juil. 2009 : 19:07:11
The most likely did notify their authorized vendors / resellers. Not all stores that carry Garmin units are authorized vendors / resellers though.
WmLane Posted - 01 juil. 2009 : 18:51:41
You would think that Garmin would notified their vendors of this issue, sort of like a recall.
Hogster Posted - 01 juil. 2009 : 18:29:50
Great news Kflint! I wonder if their method of 'fixing the problem' involves uplugging the battery and installing firmware version 3.60 ..... Glad to hear yours is on the way back to you! When I was in Halfords this morning a chap with a 765T box came up to me next in the queue! His had died and he was returning his for a replacement too ... I've also warned the guys at Halfords to caution customers with replacement 765s to update the firmware immediately to 3.60 .... his first reaction was that 'Garmin said to replace the unit so the new one should be fine' ..... um, replacing it with old stock? Think they'll be seeing that again very soon if they don't upgrade the firmware!!

Cheers


David
Kflint Posted - 01 juil. 2009 : 17:13:52
I e-mailed Garmin to check on the status of my 755t, which I shipped to the service center on June 23. Garmin responded, "We have found a way to fix these units instead of exchanging them so you will be receiving your same unit back. Your unit has already been fixed and is shipping back to you as we speak." So it looks like everyone will be getting back their original unit.

Garmin shipped it back to me on June 29 by UPS ground. I should have it tomorrow.

Hogster Posted - 01 juil. 2009 : 15:36:38
Hi peking,

Thanks for the advice, someone mentioned that a while ago What a situation that would be - to have the replacement die because I was too keen to use it! Strangely the store didn't tell me anything about the need to immediately update the firmware to 3.6 .... maybe I should suggest that to them ....

PS. cgr - Yeah they were very helpful! Especially that they said they would find a 765 to replace mine even though they don't actually sell the product any more (why, I don't know!) ...

Good news for Hogster...if I ever make it to the UK, I'll check in with Halfords...sounds like a good store! Glad to hear you'll be up and running soon...I guess we'll never know how they managed to exorcise the Bluetooth out of your old 765!
peking97 Posted - 01 juil. 2009 : 13:16:18
Don't forget to update it straight-away as it won't have Ver 3.60 installed out of the box. Don't let it power-up and start acquiring satellites. Plug in the USB cable and let it power up in Mass Storage mode, run the Garmin WebUpdater and install ver 3.60. Dont touch the On/Off switch, rather disconnect from PC and let it boot up normally as that is when the actual install takes place. HTH
Hogster Posted - 01 juil. 2009 : 12:48:32
So, went to Halfords today, they said they couldn't give me a refund, but they would check their warehouse to see if they have any spare units in stock .... that was 0900, it's now 1150 and I've just had a call saying they've got a new unit in for me and I can swap it with my old unit later today!!

All's well that ends well!

Cheers!

Hi peking97,

Sadly there is no Bluetooth icon in the Settings menu at all .... nor is there a Bluetooth Test Page in the Diagnostics menu, nor can you press the 'Updt BT' button in the Bluetooth page you get after pressing and holding the speedometer .....

Serg - Good call ... I've just been reading the User Review thread for the 8X0 series and I think I'll stick with getting another 765! It does everything I want it to, quickly and easily ...

Let's see if Halfords agree to give me a refund first .....

Cheers

Have you gone to Tools> Settings> Down Arrow (Bottom Right)>...you should see BT in Bottom Row Centre next to Security?

I just got off the phone with Garmin. I was just trying to verify that they got my unit, which I shipped 2 day priority mail to them last Wednesday. The support person said that they did receive it and the same unit was shipped backed to me yesterday. She did say that it is likely that my favorites will be gone. No biggie for me. I just want a working unit. Would be nice if I got it tomorrow. I was planning a road trip to southern Ohio on Thursday and thought it would be nice to have it. I'll have to break out my iQue 3600 LOL
SergZak Posted - 30 juin 2009 : 23:29:47
You might want to do a forum search for the 8x0/8x5 series (same as the UK 860T etc series) as they seem to have their own issues...
Hogster Posted - 30 juin 2009 : 23:14:00
Thanks for your reply IsLNdbOi ... I am quite tempted by the 860T actually ... with speech recognition, not having to press buttons whilst driving would be very useful!

Well, let's see what they say ..... I've got the original receipt and the box has the same serial number as the unit on it ...

Again, I will keep this thread posted . Sorry to take this thread slightly off track by the way, but everyone's input has been so valuable!

Many thanks again,


David
synomenon Posted - 30 juin 2009 : 23:10:38
I don't know how it is in the UK, but here in the US when you return a defective unit for exchange they'll give you a full refund if they no longer have that item in stock. At least that's how it is at most of the stores around me.

They'll also check to see if the item has the same serial number as the one you purchased from them. If it's different, they direct you to the manufacturer instead of giving you a refund.
Hogster Posted - 30 juin 2009 : 23:04:22
Hi SergZak,

Sadly there is no Bluetooth Test Page on my unit at all!

After pressing and holding on the battery icon I get:

- 'SW Ver' page
- 'Version Information' page
- 'Data Card Test Page'
- 'Audio Test Page'
- 'Audio Output Test Page'

And then it goes into the screen-testing pages where it flashes up in different colours ....

I will see what Halfords have to say, but then I might just bite the bullet and send it back to Garmin again ..... but I'm slightly concerned by comments from others who've had Garmin reps tell them there are no 765 units left because they're all being modified ... or whatever their wording was ....

Looking at the current range of units Halfords offer, the only one which I would be content with having (feature wise) is the 860T which would cost an additional £150, assuming they would allow the cost of the 765T to be credited to my card ......

Will keep the thread posted ....

Many thanks for your input,


David
SergZak Posted - 30 juin 2009 : 22:47:54
@ Hogster

I will mention again that all links you're finding & posting are regarding the Bluetooth on earlier units (3xx/6xx/7x0) which used the Parrot Bluetooth chipset While the 7x5 series and other newer units use the Texas Instruments Bluetooth chipset...both are entirely different animals. I have never heard of any Bluetooth issues nor fixes as you're describing with the newer 7x5 units.

You can play around with the diagnostics page that was mentioned...press and hold where the battery icon is for ~7 seconds to enter diagnostics, then press the "next" button five times to get to the Bluetooth Test Page. This is what the Bluetooth diagnostics page looks like:



If you don't even have a Bluetooth test page anywhere within the diagnostics mode, there is definitely something hosed on your unit and you should contact Garmin for a replacement...which at this time with tons of returns from other borked 7x5 units will be admittedly slow in getting to you.
Hogster Posted - 30 juin 2009 : 22:33:39
cgr - I did have a look at that menu earlier, but didn't find anything of interest ... On your recommendation I've just looked again .... and there is no "Bluetooth Test Page"! This nüvi is absolutely convinced that it doesn't offer Bluetooth functionality!

I'm going to try going into Halfords tomorrow, armed with my original receipt, and ask what their policy is on replacing faulty devices which are no longer part of their stocked product line ...... I really don't want to have to send it back to Garmin yet again ......

Cheers


David
cgr6513 Posted - 30 juin 2009 : 22:22:50
Hogster - If you hold the battery icon on the main screen of the 765, it will go into a series of info pages...hit next about 4 or 5 times and you get to the "Bluetooth Test Page"...from there you're on your own...but you could try playing around with some of the buttons...including the "reset device" button....I don't know what all this means...but it probably won't destroy your unit! Good Luck.
mmaslar Posted - 30 juin 2009 : 21:49:13
Nice... I mailed mine to Garmin in Kansas on Tuesday last week. They received it on Thursday. They are holding on to it and won't ship a replacement yet. Apparently, they do things differently in Canada. It sucks they won't send a new one or fix mine. It's frustrating just waiting.
jimy3000 Posted - 30 juin 2009 : 21:45:43
fyi..only saw this thread today...my story ..i'll make it short..
755t
1. last wednesday..same as everyone..gps updating..restarting..then later on in day..dead....
2.called garmin..on hold 45 min..tried all the normal fixes..nothing..they said to wait 24 hours for battery to reset..lol..not..
3. thursday mailed to repair site(note: in canada we have to send to a quebec electronics company for repair)...mine under warranty so i wasn't going to try opening it..if not under warranty i would
4.they acknowledge reciept on friday..and they will let me know how it goes...way to go Canada Post..overnight service
5. Monday my email say it is being shipped back to me...wow
6. today(tuesday) received...repair order said 'firmware updated...tested and working
7. i updated on internet..it was ..only some voice updates i added
8.tested in car...traffic works..all my waypoints still there.
9..diagnostics..had one phrase..'abnormal shutdown'....

that's it..


mmaslar Posted - 30 juin 2009 : 21:42:59
Well, at least you gotten yours back. They won't send mine back to me. I've already been without it for a full week, and they anticipate another full week before they even send my replacement.
Hogster Posted - 30 juin 2009 : 21:37:54
Hi SergZak, thanks for your reply

I don't know whether to be pleased or disappointed, but the Unit IDs are identical .... so somehow Garmin have !&@^%&-ed the Bluetooth module ......

Seems my options have run out then ... I've reinstalled the 3.60 firmware again but it's still the same ... interestingly I found these people who had exactly the same problem but found no solution:

http://www.fixya.com/support/t638510-garmin_nuvi_770_bluetooth_problem

*sigh* I would really prefer not to be without the unit, particularly for this coming weekend .... I'll just make do for the time being .... and if/when I do return it I certainly won't be waiting 14 days!! They stuffed the unit up, they'd better get it back to me as soon as possible!

Thanks for the help guys, it's much appreciated,


David

You mention the serial number and case scratches are the same. Maybe Garmin repaired your unit by reusing the same case/serial number but mistakenly swapped your 765 mainboard with a 755 mainboard...this is entirely possible but not very likely. Regardless, who knows exactly what they're doing to repair these units and how fast they are trying to do it. They could have them side by side on a repair line and mixed the guts up.

One way to verify it's REALLY yours is to verify it with the Unit ID number. Touch Tools>Settings>System>About and compare the unit ID displayed on nuvi to the unit ID listed for your registered 765 on your myGarmin account (don't confuse this with the serial number which you said was the same).

If the nuvi's Unit ID matches what is on your myGarmin account, then somehow Garmin borked the Bluetooth module on your 765 and should now repair it.

If the unit ID's do NOT match, there must have been some mix up when they repaired/reassembled your unit.

The Bluetooth fix procedure you mentioned in the link is for the older 3x0/6x0/7x0 Bluetooth models which used the Parrot BT chipset. The 7x5 series uses a TI (Texas Instuments) BT chipset and AFAIK, the Bluetooth module firmware is embedded in either the DSP software or the unit's main firmware. There has never been a Bluetooth update for the 7x5 series.

See the nuvi changelog links pages here:

http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=125920

Scroll down to the nuvi 7x5 series section.
Hogster Posted - 30 juin 2009 : 20:30:25
Tried reinstalling the version 3.60 software and nothing's changed, even after yet another hard reset .... how is this possible?!

The post by ggraves in this thread looks promising:

http://www.blackberryforums.com/general-8300-series-discussion-curve/95302-bluetooth-sync-problem-garmin-nuvi-680-a.html

But I can't find the 006B055301.GCD file he mentions ....

There has to be a way to fix this!

Many thanks for your thoughts / ideas

Hi Jon,

Many thanks for your reply

One of the things the Garmin rep suggested I try was the hard reset, and sadly this made no difference to the situation! Very strange ....

I will post here as soon as I've reinstalled the firmware ... hopefully that post will be full of 's !!

Cheers


David
jonstrong Posted - 30 juin 2009 : 17:24:19
David - you might also want to try a system reset while you're at it (press lower right of screen while powering up). I don't know for a fact that it will make any difference in your situation, but with devices like this (and various cellphones, routers and other firmware-dependent electronics), sometimes a full reset does more to restore normal function than a firmware load by itself -- all depends on the design and implementation of the system software and hardware. I agree that it's worth trying a reload of 3.60, but would also add in the reset.

- Jon
Hogster Posted - 30 juin 2009 : 16:26:53
Ok I will try this when I get home and keep my fingers crossed!!

Cheers


David
cgr6513 Posted - 30 juin 2009 : 16:02:27
When I was having BT issues a while ago on the 765t, the rep told me that the software is integrated into the system and not in a separate directory as in earlier units...so, maybe just reloading 3.60 will help...don't see how it could hurt....good luck David!
bluzark Posted - 30 juin 2009 : 15:47:02
"Is it possible that when they did whatever they did inside the unit they disturbed the Bluetooth module / connector? Is it worth opening the unit to see if any connections have come loose?"

Hardly, since the bluetooth chipset is nowhere near the battery connector and it is assembled to the main print so I can't come loose by accident

I fixed for about 40 nüvi's by now, no errors afterwards.
all happy customers :D
Hogster Posted - 30 juin 2009 : 11:36:26
GREAT! Now I find Halfords no longer stock the 765T (not on their website or in their store) so I can't take it back for a replacement!!!!

I'm going to try running the Web Updater this evening to see if it can update the Bluetooth firmware, but as I can't even see what the current firmware is I'm not holding out much hope. Garmin said it would take 10-14 days to fix the unit if I sent it in again

NOT pleased

Is it possible that when they did whatever they did inside the unit they disturbed the Bluetooth module / connector? Is it worth opening the unit to see if any connections have come loose?

Many thanks,


David
Hogster Posted - 30 juin 2009 : 11:13:42
Right I've just got off the phone with Garmin and we ran through some basic tests, doing a hard reset, etc, but no luck ... I have a Bluetooth-neutered 765!! The lady recommended I either returned the unit to them (again) or I can just take the unit back to Halfords and get a free replacement .... which I would need to update to 3.60 .... What a hassle .......

Any thoughts or ideas?

Many thanks,


David

Downgrading from 3.60 to 3.40 will not brick N765 anymore.
NanaimoRick Posted - 30 juin 2009 : 06:11:07
I agree. Lets not try and fix a problem before one actually exists.
jonstrong Posted - 30 juin 2009 : 06:01:22
Interesting...but I'm having a hard time imagining that there's a hardware flaw that needs to be replaced since these units have been working for the better part of a year. The firmware fix makes sense, and seems to have fixed the problem for many of us.

If we now have 3.60 installed and it seems to be running well (as in my case), I'm planning to keep on using it unless a hardware flaw of some sort starts to show up -- at which point I'll come back to Garmin with the issue. Not sure I see any reason yet to assume that doing a battery pull and web update to 3.60 isn't sufficient. So far, we're only seeing that concern raised because of a comment made by a Garmin customer service rep over the phone to one person -- and we really don't know if the rep was necessarily providing an accurate factual account of the situation.

I'm still guessing firmware bug only, unless we hear more to indicate otherwise...

- Jon
synomenon Posted - 30 juin 2009 : 05:51:12
Backdate firmware to one that will brick it. Don't tell them you "fixed" it when it bricked the first time or they void your warranty.

Or you can talk to them and try to work something out?

It's not confirmed anyway. That's just what this manager told me.
cgr6513 Posted - 30 juin 2009 : 05:47:10
If they all need rework...what happens to those of us who "fixed" are own??

synomenon Posted - 30 juin 2009 : 05:30:42
At first, the manager at Garmin I have been in contact with said that I would get my own unit back since they do not have stock of any 7x5 unit anymore. Then I got another message saying that all of the 7x5 units need to be "reworked".

Not sure what's happening now. Seems like more than just the software update was needed to fix these units.
mmaslar Posted - 30 juin 2009 : 02:45:06
The woman I talked to today said that they will not be sending my original unit back. That's why I have to wait for a new unit. I will let you know when I receive the unit if it is in fact a new unit or the one I sent to them though.
h2ocean Posted - 30 juin 2009 : 02:35:51
I am curious if they will send you a replacement unit or send your unit back since it seems that it is a firmware update which fixes the problem. Can you let us know if they send your original unit back to you? Thanks!
mmaslar Posted - 30 juin 2009 : 02:23:52
I think we all know about the battery fix for the dead units by now. It's been well documented throughout this thread. The point of my post was for those who didn't want to risk opening up their unit for fear of voiding their warranty. I figured I would post an update concerning what Garmin told me about the status of the units that were sent back to them.
h2ocean Posted - 30 juin 2009 : 02:17:15
My 755T also shut off and refused to power up. I simploy removed the cover and unplugged the wires connected to the battery for about a minute. It powered right up (had the WebUpdater already started on the PC) and connected the USB cable. It launched right into the new update which fixes the problem. It took me 2 minutes to open, disconnect, and close the unit. Just use the right Torqx 5 screw driver so you don't strip the screws.
mmaslar Posted - 29 juin 2009 : 22:20:53
The rep told me they were waiting on new units rather than repairing my old unit. It seems like they found something wrong with the hardware on the models that would no longer power on, and they are working on a new model. She said they informed her that they "should" be ready to ship in the next week or two, but she was going to send me email updates every couple of days and also a final email when the new unit actually ships. She was very friendly. Let's hope this process doesn't take too long.
synomenon Posted - 29 juin 2009 : 22:16:09
The manager I've been in contact with used the same word, "overhaul". I told her that if they aren't sending me a new 765T they better send back the one I sent them (in working condition).
mmaslar Posted - 29 juin 2009 : 22:12:30
I just talked to a Garmin rep today and she said that they received my unit but are waiting to get new models in stock. Apparently, they are overhauling the units. Has anyone else been told this as well? I sent mine in last week (the 23rd) and they received it on the 25th. I hope they can get these out quickly, as I will be moving in three weeks, and my current address will no longer be correct.
reicher Posted - 29 juin 2009 : 21:29:26
is anyone else having issues with no traffic/cradle not charging the unit after the upgrade?
My device (a 765T) wouldn't acquire - Garmin released patch - I patched and all seemed ok.
But, the unit will now only charge on USB connected to the PC and no traffic now, which is pretty much why I bought the thing since I know the way to work.

What now?

@IsLNdbOi
Too late for that! I purchased the card in April when I bought the Nuvi so everybody's been paid and I would have no leverage to pressure them. I think I can eventually get them to do the right thing, (If I go far enough up the food chain) but it's the hassle factor to get them all to do it!

The good news is that based on some posts here and posts on other forums it looks like I should get my own unit back. This would eliminate the problem entirely

@NanaimoRick
Thanks for the info and suggestions..... much appreciated!
I called Garmin, The CS rep is sticking by the 10 to 14 day turnaround and said the best she could do would be to put a note in the system along with my Return number explaining that I needed it ASAP. She Can't/Won't guarantee anything past that and did not know if they will ship it back using 2 day, priority or ups. With the 4th of July being Friday and them not open for the weekend it's not looking good for me as I'm leaving July 9th.

One bright spot though ....... It appears as though I should get the same unit back and that will eliminate the MSN direct subscription problem!.........small yay!!

Nope this is definitely my unit. I recognise the worn serial number and the scratches on the case (as unlikely as that sounds!) ...

In the system information menu (pressing and holding on the speedometer) it says the Bluetooth address is 'Not Set' and under "Enabled" it says 'OFF' ...

The software version is 3.60 and the GPS software version is 2.80. What have they done to my nuvi?! ...

Hi all

Garmin did return 'my' nuvi but all my Favourites have gone Seems they just wiped the unit and put new software on ... That didn't overly bother me, but I've now discovered that Bluetooth no longer works on the unit!!! There isn't even a Bluetooth option in the Settings menu! WTH???

Any thoughts on what I can do to fix this?

Many thanks,

My Nuvi 785t Died late last week and is one of the units that won't power back on. I sent it back Sat, before finding out in the forums that it could be fixed by the using the "unplugging the battery trick".

What a mess! I purchased this Nuvi 785t for a vacation trip that is 10 days off, and Garmin say's 10 to 14 days turnaround (not including holidays or weekends). This means I probably won't get it back before the trip (they are verrrrrry sorrrrrrry!) and there is nothing that they can (or Will!) do to expidite the unit.

........And it gets Worse!!

I had also purchased and activated a pre-paid lifetime subscription to MSN Direct the day before my 785T died. MSN Direct has informed me that because I bought a "pre-paid lifetime subscription" through Amazon (or apparantly any other seller), it is only good for the unit it was assigned to and would not be transferable in the event Garmin replaces my Dead unit. They informed me that If I had bought the subscription directly through MSN then it would be transferable. Garmin disagrees and say's "not so" They claim that it would be transferable no matter how it was purchased.......... I agree with Garmin, It should not matter how I buy or pay for the subscription, but MSN says "Them's the rules."
I think it's going to be a long protracted battle that will depend on whether or not Garmin fixes or replaces my dead 785t.

..........And more good news!!

Garmin will not reimburse for shipping your dead unit back to them, Even though they actually caused the problem. That's their policy!
It's not something that they would have no control over, like a component failure. This problem was caused by and is totally on them! ...... but their policy is their policy........ what a lovely way to treat your loyal customers!

I'm not so high on Garmin right now! .......or MSN Direct for that matter!
Hogster Posted - 29 juin 2009 : 11:35:19
The unit is at home and I'm at work so I don't know! ... I also don't know the serial number of the old unit ... I do remember where there were scuffs and marks though, and I know that the serial number was nearly worn off, so it should be quite easy to know if it's the same unit or a refurb ...

Cheers


David
synomenon Posted - 29 juin 2009 : 11:03:12
Is the serial number on it the same as the one you sent them?
Hogster Posted - 29 juin 2009 : 11:00:34
Just to say that my bricked 765T has been returned to my home address Not sure whether my Favourites are still on it, but still, I'm grateful their turnaround was so quick (I sent it to them on the 24th).

Shame I sent it off to them before you guys discovered the units could be repaired without sending them to Garmin, but I'm only a few quid worse off for the postage, and I might need to rebuild my Favourites again ....

Still, lesson learned

Cheers

It would seem that the mandatory update would make it unwise to back-level the software/firmware in the affected models for any purpose. I know the back-leveling method has been a common practice with advanced users for testing and/or to resolve problems introduced in new versions.

Information I collected on forums is that only 3.40 causes that sudden death. But lost satellite reception and incorrect position fix can occur with older firmware versions too. Version 3.60 is mandatory update. More people reported that update from an older version to 3.60 went well.

Hi..

I currently have the firmware 3.60, when I run Webupdater, it lists me the "GPS Type M" update.

Do I have to update my unit with this?, I updated it sometime ago, before my got bricked days ago. After I could unbrick my unit (765T), I deleted some files from remotesw folder as I read on these posts. Is this update fixed or is the same one ?

Thanks

My 755T works fine and has traffic updates after the 3.60 fix.

When I got home from work Tuesday evening, I put my "spare" 765T in. It worked great this am on the way to work.

At least this may indicate that if the Nuvi 765T was NOT on Monday 6/23 it may not have a problem. I won't be able to check it again until tomorrow evening since I have to take a company vehicle home tonight.

Just my observation.





Well when I got back into work from my field trip, I got into my car turned on my 765T and it died. It really died. I made the mistake of pulling it off of the mount and it asked me if I wanted to turn the receiver off. I made the mistake and said yes. When I got home it would not power on.

I sent an EMAIl to Garmin and got a RMA from the. It is now on it's way to be fixed.

I have a 755T...got the e-mail from Garmin...downloaded the 3.6 fix.

After disconnecting, unit said "battery was low", so I charged it using ac charger. Battery charge seems ok now.

I drove for the first time since updating, and now I can no longer get traffic. Since I live in Houston, and there is always traffic, I assume there is a problem with the unit caused somehow by the 3.6 fix.

I tried updating traffic device via webupdater, but still no traffic.

Anyone have a similar experience?

I just wanted to echo the comments above...the sense of relief I felt when I found this thread and was able to unbrick my 765t myself was just great...I couldn't believe how many times I glanced at the empty cradle for the ONE day the Nuvi was out of commission! I guess I rely on it more than I realize...even to see how fast I'm going! Thanks again to all the contributors of the forum...and to Garmin for a very quick turnaround on a patch.
synomenon Posted - 27 juin 2009 : 08:07:05
Now that many of us have sent our 7x5's back to Garmin for "repair", what are the chances the unit we receive (if it's not the same one we sent in) does not have the touch screen accuracy / calibration issue?

My 765T had this issue, but I learned to live w/ it.


*Oh and those who have done the latest update to "fix" the unit should do a hard reset after the update just to make sure you don't have any other problems.
daveo Posted - 27 juin 2009 : 07:01:28
My calculations say that a powered off Nuvi 755 takes 4-6 days to completely discharge. This is based on it being 75% charged after 24 plus hours. I bought the screwdriver, used an old credit card and small screwdriver and all went quickly.

I did have an issue today while navigation a route and showing some things to a friend that it shut off and lost the route. Had to turn back on and tell it to go to the place again. Not long route, and I had driven it the other direction before, but a pain.
jonstrong Posted - 27 juin 2009 : 05:57:43
I ran into this with my 755 just a couple of days ago. I had been using my Nuvi every day when I first bought it, but since my job changed a month ago, it's been sitting in my armrest compartment most days, and I hadn't used it in more than a week. When I powered up a couple of days ago, I got the exact same symptoms reported here already:
- Updating firmware, update complete
- display frozen, couldn't acquire satellites at all
- finally gave up, turned it off, and it wouldn't turn on again after that

I just finally came over to the PC to check the forums and see if I had somehow bricked the unit myself, and found this thread. Much as I wouldn't wish problems like this on anyone else, I was thrilled to see that I wasn't alone (misery loves company!).

Just read through all 21 pages of the thread, and have to say how glad I am to have joined the forum in the first place, and what a wonderful resource it is. Long story short: I found my T5 driver (I have a nice Husky torx driver from Sears with 4 double-ended reversible tips, giving me all the sizes I need to mess around with cellphones and the like -- and now Nuvis too!). I popped out the two screws, and quickly removed the back using just my finger nails to grab the edge of the case. Unplugged the battery for 30 seconds, reconnected and closed it all up again. Plugged the unit into the PC's USB cable with Web Updater already running, and the update for 3.60 ran just fine (I also wound up downloading updates for the US English, British and Australian TTS voices as well).

I'm in my basement office right now and don't expect to get a lock on satellites from here, but I've got the unit on and it's searching normally as I type this. After reading the thread and instructions here, the entire fix took perhaps 10 minutes start to finish. Thanks SO much to everyone who has contributed to this. This one thread saved me having to be without my 755 when I was about to start making daily use of it again, and saved me the hassle of dealing with the RMA process.

Happy ending to a stressful day!

EDIT: took the unit out front and sat on my porch for a few minutes, and acquired satellites and found my location. Seems to be working just fine now, and I'll take it for a navigating spin tomorrow. One other bonus to the experience: now the process of replacing the internal LIon battery is no longer a mystery, so when that starts to slow down in a year or two, it should be a piece of cake to replace it. Thanks again everyone!

I have a 765T. I was on vacation on Monday 6/22 when my unit went through the "GPS update" like everyone else, and then my unit was bricked. I used my laptop from the hotel to do some research on how to unbrick the GPS - but I found that I had brought the wrong laptop power adapter, so I only had one charge worth of battery power, so I didn't find this forum right away. Wednesday when I got home, I found this forum and this very informative thread.

I decided to try and open my unit myself rather than going through the hassle of sending it back, and possibly getting a refurb unit back that I wouldn't be happy with (scratched, etc).

I waited a few days, thinking that maybe the battery would drain out on its own. I even spent a lot of time just pushing the power switch over to "on" and either holding it, or releasing it, thinking this might help drain the battery faster. Since there was no screen backlight, I figured it might take longer, but that the battery should eventually drain.

Today I made the trip to Home Depot to get a Torx T5. The screws came out easy. I didn't have a spudger tool, but since some people said credit cards worked, I tried that and it worked pretty good. I'm visually impaired and mechnically a klutz, so if I was able to do it, anyone can.

TIP: Use two old credit cards. After you take out the screws, pry apart that part of the case with your hands and slip a credit card in as far as you can get it to go. Then use a second card to work your way towards the left corner. Once you have that in, take out the first card and work your way around the corner onto the left side. Use one card to hold open what you've done while you use the other card to pry. Once you get about halfway around, it comes apart very easy.

You don't even need to unplug the battery for very long. 1 second did it for me. I ran the software update before I put the unit back together.

Thanks to everyone in this forum for the very informative information.

- Bob

Well after my 755 went dark on me, first place i turned was you guys. I haven't used my car lately as I've been riding my bike, but first time i used it in over a week and kaplooey!

Followed directions on how to open up and unit is working great after software fix. If i can do it anyone can. Just make sure you use the right sized Torx T-5 driver. came apart much easier than the video showed!

Thanks guys
SCVJeff Posted - 27 juin 2009 : 02:45:03
BTW- I bought this GPS from a camera shop off eBay(New), and it was delivered Tuesday morning with 3.6 installed. Maybe they saw this coming?
NanaimoRick Posted - 27 juin 2009 : 01:46:42
I don't think safe or wait is an issue. Since 3.60 was created specifically to fix the major problems reported this week, your going to have update or run the risk of not having a working Nuvi at all.
rookie8155 Posted - 27 juin 2009 : 01:02:20
So if you have firmware version 3.60 on Nuvi 765T, is it safe now or should I wait?
I will appreciate your advice.

Looks like it is happening in the US as well. Amazon.com show:

Currently unavailable.
We don't know when or if this item will be back in stock.

Best Buy don't have any of the 7x5 series on their website at all.

Gpscity.com still show it as available as of a few minutes ago however.
BAVC10 Posted - 26 juin 2009 : 15:11:52
Existing Nuvi 765T is completely dead - won't connect to webupdater so took back to the store I purchased the unit from for a refund and ordered a new one from their on-line site.

Received a call to say the order couldn't be fulfilled as Garmin had requested all stock to be withdrawn from sale so that a bug fix could be applied to the satnavs. Rang a store to check this out and was told that these models were temporarily unavailable.

Whilst this recall refers to the UK have Garmin done the same in the US, rest of Europe??

This must be costing Garmin big time in terms of lost sales, replacing units and having to recall stock.

Before the update I had the firmware version 3.50 (which some of you mentioned as unpublic).That leads me to the speculation, that maybe not all the units are hit by this problem. I have a friend, he bought the same model few weeks ago, he also has a 3.50 installed by default a experienced no problem over the last week.


Yes, I've heard of others that had 3.50 factory preinstalled with no issues. This makes me wonder if Garmin already had this fix in place with 3.50, then released it publicly (although too late) as 3.60. Maybe this is also why it was released so quickly (1 - 2 days) after the problem was reported. Lets hope they can expedite the correction in the other affected units.

@SCVJeff
IMO It is normal if you chose additional files like "Text", "Translations Files", "Help Files", "Proximity Alerts", etc. after upgrading main firmware -> 3.60 in first step using WebUpdater.

If you stop WebUpdater before above mentioned, additional updates you shouldn't see "Upaditng Completed" white windows.
SCVJeff Posted - 26 juin 2009 : 11:05:39
Reading through this thread and just looked at my 2 day old 765T with v.3.6 installed. It just came up with 2 Update Complete windows before I shut it down. Does this sound like the same thing?
iNDYCZ Posted - 26 juin 2009 : 10:01:28


Platic tool is not required, just use your fingernails.
btw. thanks all for guide to fix my dead garmin 765t, now is after disconnecting battery and upgrading firmware alive. ;-)
Sorry for my bad english

hi,
i want to share with you my experience. I bought brand new 765 on 09/06/23. On the same day I found this forum, so I avoid to use my unit for navigation. Just to be on the safe side, I renamed those two files mentioned by Sergzak and waited for release of new firmware.
Yesterday I did the update for 3.60. Everything looks fine now. I have checked those file and found out, that the new ones installed are exactly the same size as previous which I have disabled.
Before the update I had the firmware version 3.50 (which some of you mentioned as unpublic).
That leads me to the speculation, that maybe not all the units are hit by this problem. I have a friend, he bought the same model few weeks ago, he also has a 3.50 installed by default a experienced no problem over the last week.
I dont know, whether my conclusion is correct. If you have the similar ar opposite experience, please comment.
SergZak Posted - 26 juin 2009 : 05:37:58
They likely need to reflash ALL of their stock (both new & refurb) to the 3.6 firmware version.

I think this is a first for Garmin...not enough stock (new & refurb) for the literally thousands of exchanges. So now they will actually *repair* (not send a refurb) your unit which will involve exactly what others have been doing with their bricked 7x5's. That is, open the case, unplug the battery, plug it back in and flash v3.60 to the unit.
synomenon Posted - 26 juin 2009 : 05:23:43
I received an email from a Manager at Garmin today saying:

"
I was attempting to get your gps out tonight and expedited however I received a message back from the warehouse indicating that we do not have any 7x5 series in stock that is ready to go out. Unfortunately all of these devices including new ones have to be reworked to get the issue resolved. I did notify the warehouse that your device is expected to arrive in our warehouse tomorrow. I did find out that we might actually be doing repairs on these devices so if you have any favorites saved, those will still be available. I want to clarify that this option has never been available until today as we don’t have enough stock on hand to exchange everyone’s 7x5 device and the fix is simple.

The good news is since we know what the issue is and how to correct it, it should be resolved fairly quickly and you were able to get your device to us in a timely manner. We process each exchange in the order they were received, so hopefully, you should be taken care of quickly.
"


I responded, asking what she means by "all of these devices including new ones have to be reworked to get the issue resolved".
Regulator2 Posted - 26 juin 2009 : 04:00:53
Thanks to all on this forum for the help in explaining what the 7x5 problem was and how to fix it. My 6 month old 755t started to fail yesterday with power and satellite issues. Today it could not acquire the satellites and then would not power up. Luckily I held the power button to the left for 12-15 seconds and it powered up, on the battery. Immediately did the Garmin web update, and all went well. Used the unit this afternoon, and it was back to its normal operation. You sure miss it when its not working/available.
rcalpha Posted - 26 juin 2009 : 03:13:48
My 765T is alive again, it was bricked. Thanks to SergZak and bluzark for sharing the fix. I was afraid to open my unit because It's 2 month old. This procedure saved me about 80 USD for shipping for repair (I'm in South America)
SergZak Posted - 26 juin 2009 : 01:13:14
Mods: maybe v3.60 firmware observations should be in a new topic? There may not be much to discuss yet though since it was seemingly only a bug-fix...

Here are a couple of personal observations of 3.60:

1. For me, sat fix time seems about the same with no difference one way or the other in performance
2. "Slide" effect between screen changes along with map redrawing is noticeably smoother. Overall feel of the unit seems snappier.

I recall a few posts stating that user's recent NIB 7x5 units came factory pre-installed with firmware 3.50 (not a typo, 3.50) which would be an internal Garmin release. It could be that there are more bug fixes/tweaks/new bugs carried over from 3.50 in addition to the main "GPS sat fix" correction that is being reported by Garmin. They have done this in the past.

No one knows for sure what Garmin's fix for the "GPS sat fix" issue was except for Garmin themselves. If HotFix (or AGPS) was disabled or not is unknown.
dsrussell Posted - 26 juin 2009 : 00:45:53
Here is an odd result from the update. My 765t has been pretty fast acquiring satellite signals (usually under a minute on cold starts and only a few seconds on warm starts). After the update, I'm acquire the satellite signal much faster (cold starts are a few seconds, and that is inside my house). I thought this fix disabled "hotfix".
daveo Posted - 25 juin 2009 : 23:30:02
I went to Lowes while out visiting clients and stuff. Took longer to pry case apart and back than anything else. Use a PC small flat head and an old credit card. Took a couple tries to get it back together, but thanks to all for sharing. I was post 2 on this list. I agree with the above poster - I might not see this unit until AUgust if I sent it back and I do work on PCs, so it was just a matter of scale for the screws. The connector for the battery is a common one.

Thanks for the info everyone.I now have my 755T back up and running after opening her up.For the record mine took a T6.

Unscrew both torx screws



Use a plastic tool to unlock the cover



Work your way around the unit







The top side of the cover has 3 locking points and the sides 2




Release the battery connector for atleast 30 seconds



Rebuild your unit and connect it to your computer
Install the update via WebUpdater



Wait... :D



Voila!

Well, I bought a T5 torx driver this morning and opened up my 755T.
Had it back together and updated in less then 10 minutes.
I wasn't prepared to pay to send it back and be without it for 2 weeks (at least).
chuck350 Posted - 25 juin 2009 : 15:23:52
daveo,
I didn't use a T4 or a T5 screwdriver, I had a small flat blade driver for eyeglass repair and it worked fine.
I once RMAed a video monitor to ViewSonic and they lost it for 6 months.
Garmin is going to be overrun with returns!
beckp Posted - 25 juin 2009 : 14:59:35
Did the update for 765T last night, by the time the installs finished after I disconnected it from my computer, I had all the bars on Sat strength. Haven't used it for any navigation yet. All seems fine.
boaterbob Posted - 25 juin 2009 : 14:34:07
Done with update. Now at S/W version 3.60 - all other configurations remains the same - still have latest maps - everything works - sats found quickly while sitting in the house.

Download/update via computer took about 30 seconds, then GPS unit updating took about 1.5 minutes.

Thanks again
Robert in SC
SergZak Posted - 25 juin 2009 : 13:46:40
@ boaterbob

Update the unit ASAP. Do NOT even turn it on long enough to acquire a satellite lock. Plug it directly into your PC's USB port (don't power it on first either) and update it via WebUpdater. Even though your unit is still working now, you may have yourself a brick the next time you turn it on and get a sat lock. This is a mandatory update.
boaterbob Posted - 25 juin 2009 : 13:38:34
For all of us with the following 775T configured units:
S/W version - 3.40
GPS - 2.80
GTM - 5.50
Maps - 2010.10
Units still seem to work ok

Should we go ahead and do the 'fix' install? If the 'fix' will do no harm, then we may as well do it, however, if there is no need to 'fix' this configuration, then maybe best left well enough alone (as some one earlier said they did the 'fix' and lost their 2010 map updated they did during their 60 day window).

Thanks for the excellent posting.

Robert

@ FXDWG

Garmin indeed uses two different screw sizes on units, even within the same series. They have been known to use both Torx T4 and Torx T5 as you've discovered.

Haven't backed them up since April.

My wife had my unit on Monday. Didn't tell me it was losing satellites and rebooting on her. She thought it was from the heat inside her truck. I couldn't even get it to turn on Tuesday morning.



I checked my screwdriver twice and it has T5 written on it. I tried the T4 and it would not unscrew the screws. It could be that Garmin is using different screws depending on the supplier.
