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

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
||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 ?

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 ...)

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.

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.

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...

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.

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?

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.
||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.
||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.

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?
