Grrrr...Rick, you beat me to it.

I will wait for all those running 4.0/4.1 to give this release a clean bill of health before installing on my 3.1/3.2 units.

Although I suspect that there are other changes besides what is shown in the change log (normal for Garmin) I did want to report that the update went smoothly. I did notice the 760 took a long time to reboot the first time after the firmware was installed. The software loading message stays on the screen for probably a minute or more, which is a long time when your worried about 'bricking' your GPS.

So far all other boot ups have been OK with no long "loading maps" occurring.

Can't say as I blame you for waiting if you have 3.1 units but for all the folks with 4.0 or 4.1 I see no reason to wait as you couldn't be any worse off ;-)

In a simulation test on my 750, the .1 mile voice lag in 3D mode appears to be fixed. Although I notice that when the voice starts the map freezes for a second or so. The voice doesn't freeze, just the map. So my guess is there was an issue with the processor being overloaded, and to fix the problem they decided to suspend the map refresh while the voice started. Just my guess.

I haven't had a chance to test it yet in real world driving.

But again, using Jill and 3D view, the .1 mile voice lag seems to be fixed.

To those who had 760's/770's & broken Bluetooth due to backdating from 4.x to an earlier version (and still have the issue), it would be interesting to see if this release fixes the broken Bluetooth issue without requiring a trip to Garmin. Please post your findings.

Just back from a short 6Km drive around the area. I find the LAG between the announcement and the distance to turn shown on the screen to be COMPLETELY fixed. Now when the 760 says in 500 meters, the screen reads 500 meters to the turn.

Forced a number of recalculations. The first one seemed slow but after another 3 I think it is actually much faster to do a recalculation than with 4.0/4.1. Not sure it's as fast as the 3.1 days but anything is an improvement over what we had :)

Certainly no voice stuttering issues using American English Jack and 3D mode but I never really had that problem before anyway.

I always found that if you go to View Map immediately after the 760 booted up that it took forever to 'draw' the map screen. I don't see any improvement with this firmware release but on the other hand I don't recall a lot of folks mentioning this as an issue. On the plus side I am finding 'screen scrolls' faster with no long waits for the screen to 'draw'.

Saving a location by tapping the vehicle icon worked fine as well.

Off on a 300Km highway trip tomorrow so should be able to give the new version a workout.

Ouch...it's looking more and more like these units indeed need to go back to Garmin, unless they can come up with a software cure in the future.

My warranty for N760 ends in one month.
I bought N765 also... so I will send my N760 back to Garmin.
I dont believe that Garmin will fix BT problem with next firmware update.

Has anyone had any problems with POI dialing? In the Australian version if you select any POI and try to dial the number it will not dial all other functions work ok but the POI dialing is really upsetting me at the moment. WIll upgrade to 4.20 tonight and see if these issues are solved.

Not one to say the right words most of the time, two words however do come to mind.

UNDER THE CATEGORY - WOULD YOU BELIEVE ??

For whatever reason I checked out the Currency Converter, which hasn't worked for many firmware updates. I think they have finally fixed it. At least it worked fine setting a conversion rate for the Cdn Dollar and doing a couple of conversions to US dollars.

Does anyone know if the truncated expiration date on the traffic page has been corrected? How about the long-standing "battery charging complete" message bug? Just wondering if Garmin is/was on a roll correcting long-standing issues (like the Currency Converter bug that Rick just mentioned).

POI dialing works fine on my 760 with firmware 4.2

@GadgetGuy2008

Can confirm the short screen delay in simulation mode. Didn't really notice any delay while actually driving a route. Well check more closely tomorrow.

The boot-up time to password screen is now 15 secs on my 760. It appears to be back when 3.1 was available. The currency converter also appears to be working OK.

Anyone willing to try loading a previous version?

We know from the last version that Bluetooth breaks if you load a previous version. Since it appears 4.2 doesn't fix that problem I'd say the list of folks with a 760 and willing to downgrade would be a pretty short one :)

I wouldn't want to try it.
I don't want to send it in for the same thing for the second time ;)

I really miss the raw track log though.. :S

I did a little road test with 4.2 and found the voice prompts and distance to next turn are synchronized. There is a small screen delay at turns but I am not that worried about it because I should be watching the road as I turn, not the screen. Bluetooth always worked even with 4.0/4.1 with my Motorola anyways. It took along time but it appears they have solved the main issues.

I wanted to see if 4.2 would help me with a Bluetooth problem I was having with voice-dial. It didn’t, so I took storm018’s advice and figured out how to adjust the BT volume DOWN on my cell phone. It works! I blamed the problem on the 4.x release and it was my bad. Thanks Storm!

I'm running 3.1 and have never upgraded. Bluetooth with my Blackberry (T-Mobile) works great (except for call logging). I don't use voice dial. Was there another issue with 4.1 and Bluetooth that I should be concerned about? Should I avoid this update?

@ MarkY

Others here will be sure to mention any Bluetooth issues or corrections that 4.2 may have addressed or affected.

I think that if everything is working as it should for you, I would stick to 3.1 and try to avoid updating if you can until 4.2 has been thoroughly run through the mill. You can still run WebUpdater but avoid the firmware update by simply deleting GUPDATE.GCD from the nuvi (x:/Garmin/) after WebUpdater checks for addition updates & before the nuvi is rebooted. However, there may come a time where updating the various components via WebUpdater (such as the GPS chipset, Bluetooth, etc.) may require a certain firmware version to operate correctly...you may eventually have to update it anyways.

For now, I personally am sticking with my 3.1/3.2 750/760 until 4.2 is deemed safe.

@ SergZak

I think I'll follow your advice. At this point I'm not even sure what 4.2 will give me over 3.1. I'm definitely not going to upgrade just for grins.

This did NOT fix the routing problem. I'm glad I only tried this update on one of my 760s.
I set my starting point and ending point. (Usually my first job start and end at Home).
I add all my stops in between and when I optimize it always shows a different ending point.
I hit optimize again and it shows yet another end point. This can go on and on as long as keep hitting optimize but never will it end where I put my end point.
It's as if it's ignoring whatever I'm putting as my End point.

Still there as far as I can determine. I've had the 760 plugged in for 2 to 3 hours now and it is still showing as 'battery charging". It was almost at a full charge when I plugged it in so should be 100% long before now.


Update - just went into diagnostic mode and confirmed that the battery was 100% charged. The Nuvi still is showing 'Battery Charging'.

Another update from someone who went through 4.0 and 4.1: today's 4.2 seems to fix the lag and stutter. This is based on just some very short trips through town, but in all cases the voice announce (TTS, 3D) was right on time.

"Loading Maps" seems _mostly_ fixed. On about 10 powerups, most were fine but one was sloooooooow.

Advice to anyone with 4.0 or 4.1: go ahead and upgrade. Advice to anyone with <4.0 : wait.

Thanks for the info Rick. I'm happy though that Garmin has indeed addressed the critical issues regarding the 7x0 and they seem to now be resolved. The battery charging bug is admittedly trivial but if so, I wonder why it has still not yet been resolved. I also wonder if it also exists in the new 7x5 series...

Overall is every one happy with the 4.2 update? I was one of the suckers who had just purchased a Nuvi registered and was forced up upgrade not knowing anything different. I have 4.1 and will be completing the 4.2 update tonight. Will comment tomorrow as I will use it on the way to work.

Not one to say the right words most of the time, two words however do come to mind.

Not sure what's happening with your unit. I tested my 750 and it does not change my ending point.

I would have thought my unit was defective if not the fact that both my 760s were fine until that 4.1 update.
The working 760 is the one I went to http://gpsinformation.org/perry/nuvi/ and downloaded the 4.0 version. After I installed that 4.0 version my 760 asked permission to install an older update than what was installed. I installed it and it fixed my routing problem but all the other bugs are still there.

Hi Yall Again, Do I take it that most of these problems are/were with the 760 & 780 and not with the 750. As my new 750 isn't here yet when I register it and do a firmware upgrade will the 750 be upgraded to 4.2 or does the 750 require less of an upgrade? So many questions and so little time...........

I just tried 4.2 for a couple of hours in a 760 and can confirm that "Jill" TTS is pretty much back to normal. Average boot time is 15 secs. I tried some back roads that I'm not that familiar with and Jill TTS in 3D was pretty reasonable. I did have one instance using an imported route where the 760 seemed to corrupt the current route - the next via point became the end point with other via points, start and end points disappearing. I reloaded that route again and all was fine after that. This problem may have existed pre 4.2 though.

I think I'm imagining that SIRF on 4.2 seems much more sensitive than before. I'm getting signal from 4 sats in a bathroom with no windows, closed door and the 760 sitting in the bottom of a metal sink! I only lose signal if I cover the entire sink with my body. It doesn't seem possible and I could swear that I never got signal in that bathroom before.

RGoodpaster:

After entering in your route and optimizing it, manually set your end point as HOME and save your route. If you are starting your route from HOME and ending at HOME, enter your HOME as the starting point. This was discussed previously; if your route starts at your current location, it will optimize the route so that your current location is your starting point.

All of the 7x0 series use the same firmware update, regardless of what model number they are & regardless of the different naming convention in the direct download update files.

See what firmware version your 750 comes with, then you can make a decision. For now (at least), it is deemed "safe" to have it at 3.0 or 3.1. 4.2 is still undergoing testing by those who have recently installed it but it seems to be fine -so far-. You may still want to avoid updating to 4.2 until some time has passed.

To update to your desired firmware version, you can download that version from here:
http://www.gpsinformation.org/perry/nuvi/
Simply download the file and run it. These are all official Garmin firmware downloads & Garmin even refers to this archive site when an older firmware is requested.

When you register the unit, it will be updated (seemingly) to the newest version. However, the unit is not actually flashed until you *reboot the unit*. As long as you delete the file GUPDATE.GCD in x:/Garmin/ *before* you reboot the nuvi, it will NOT be updated. So you can register the unit and perform any of the other updates that WebUpdater may find without actually updating the firmware.

I ran the WebUpdater too and it installed the 4.2 pretty smoothly. Startup times seem fine. Will test "Jill" with 3D and audio books tomorrow. {fingers crossed}

Don, glad to hear that you were able to adjust your BT volume on the phone! My new Moto V750 allows me adjust the volume for lots of different things, including setting the master volume, but as soon as the nuvi 760 connects to it, it maxes them all out and the one I can't adjust is the voice-dial. Oh well, maybe a future update from Garmin or Motorola will help me out.

RGood, I don't know what to say. I just spent almost an hour trying to reproduce that problem and I couldn't do it. I created a new route, starting at Home, ending at Home, added 4 stops in the middle, and played around with manually reordering and optimizing and it always had me starting and ending at home. I tried another route starting at my office, ending at Home, with 3 stops in the middle, and I could get it to switch around the stops in the middle, but it never changed the "End". Are you creating the route on the nuvi itself or in MapSource? I hate to waste your time, but have you tried a Master Reset on that unit?

Geez-Louise, there Norm ... I thought I was a GPS addict, but I don't take my nuvi into the bathroom with me. The Sports section, sure, but my nuvi, uh, no.

I have Nuvi780 with 3.10 firmware. No big issues, except bluetooth. My Motorola Q locks up and reboots every now and then. For some reason, I didn't upgrade to FW 4.0 or 4.1. I was traveling. I normally keep the nuvi updated. So this was a blessing.

So Is it safe to upgrade to 4.2?
I don't have any lags\speech issues.

Thanks,

Personally, I am waiting for at least a week or two for any bugs to surface before even thinking about updating. Both my units at 3.1 & 3.2 are working just fine as they are. At the moment, I know of nothing verified that 4.2 adds as far as functionality goes. Some here seem to think 4.2 may contain some sort of functionality, perhaps for upcoming "free traffic" but that has yet to be verified.

DA MAXX, Just my opinion here, but I'd stay with 3.10 for now. A co-worker of mine also has a nuvi 760 that he BT paired with his Moto Q. He has what sounds like the same, occasional, random/intermittent reboot problem as you. We've done all of the nuvi updates as well as a firmware update on the Q itself and it still does it "now and then". I would make sure that your nuvi has the latest BT SW (version 3.10 right now) and stand on that hand until you need to do an update. Like SergZak said, you can run WebUpdater to check for a future BT update, but you don't have to (or at this point even want to) take the system update.

I tried another route starting at my office, ending at Home, with 3 stops in the middle, and I could get it to switch around the stops in the middle, but it never changed the "End". Are you creating the route on the nuvi itself or in MapSource? I hate to waste your time, but have you tried a Master Reset on that unit?



I'm creating on the Nuvi itself. I did a master reset if it means holding down on the lower right corner while powering on.
That just very well may have been the cure. It "seems" to be routing like it should now.
I'll give you an update when I get home tomorrow night as I have 29 stops in Eastern Ky. to run so I'll run both the 760s together.
I'm sure I'll be able to see if the new update made a difference compared to the 4.0

Thanks to you and everyone's help and suggestions on this matter.

Yes Ma, I did wash my hands before using the touch screen. The "old folks" have to take care of business before during a short road trip.

Toilet humor aside, it's the only windowless enclosed interior room in the middle of the house (main floor). This is the first time I've remembered the Nuvi working in a totally enclosed interior room of a house. Especially with the signal being partially blocked by a large metal object. It even works inside it's padded nylon carrying case while in the same enclosed bathroom.

Safe to say no more hidden track access with the 4.xx firmware if you should turn it off by accident?

As long as you delete the file GUPDATE.GCD in x:/Garmin/ *before* you reboot the nuvi, it will NOT be updated. I hope I don't sound like a dolt but can you please explain the delete portion of the above file/download to me. Is it done while connected to Garmin or what? [multiple ? removed, re the netiquette] MM

@ MrMusic

When updating via WebUpdater or registering the unit, the nuvi needs to be connected to your PC and while it is, it is acting as a removable disk drive (USB mass storage mode). Here, you have access to the nuvi's files (both the built-in nuvi drive and the SD Card drive) using Windows Explorer.

During either update process (WebUpdater or registration), the file GUPDATE.GCD is downloaded, then copied to your nuvi drive into the x:/Garmin folder (where "x" is the drive letter assigned by Windows to the nuvi drive) if WebUpdater sees that there is a new firmware update. After the online update process, you can access this file using Windows Explorer to delete it BEFORE disconnecting and rebooting your nuvi. If you don't delete the file, the next time you power up the nuvi in normal GPS mode (not USB mass storage mode), the firmware update will proceed.

One thing to note is that if WebUpdater sees that your unit already contains the latest firmware, no file transfer will even take place. WebUpdater looks at a value stored in the file x:/Garmin/GarminDevice.xml. If the value is less than or equal to that which is contained in the latest firmware update, the latest firmware file is downloaded, then copied to the unit & the unit's firmware is updated on the next nuvi-power up cycle. GarminDevice.xml is regenerated on every nuvi-power up cycle and is updated with current firmware version, voice versions, Bluetooth version, etc and rewritten to x:/Garmin/GarminDevice.xml

Example 1:

value in GarminDevice.xml = 4.0
value in GUPDATE.GCD = 4.0
No download & file transfer/firmware update occurs

Example 2:
value in GarminDevice.xml = 4.0
value in GUPDATE.GCD = 4.2
Download & file transfer/firmware update WILL occur

NO update will ever occur if GUPDATE.GCD is NOT on the nuvi

Hope I didn't make things even more confusing...

So change value in GarminDevice.xml = 2.3
and add `file GUPDATE.GCD version 3.1

What will happen?

Good explanation SergZak, thanks. Is Garmin using a different methodology to determine new voice updates? I notice that each time Webupdater tells me I have a huge list of new voice updates even though my unit already has the latest ones. Is that a software bug where the system can't figure out you've already got 1.20 even though 1.20 might be the latest version for that particular voice?

I feel this is a long-standing bug with the 7x0 series but could very well be wrong. It seems unprobable that the problem is with WebUpdater since my nuvi 350 is fine when it comes to the voice updates being correctly identified as being updated, though it certainly could be WebUpdater related. I have no idea which is the culprit, WebUpdater, the 7x0 or a combination of both. Neither of my 7x0 units have ever worked correctly with the voice updates & WebUpdater. My 350 has always worked...

WebUpdater compares version from GarminDevice.xml with current version on Garmin server. GUPDATE.GCD doesn't have to be in nuvi for WebUpdater to downlad upgrade.

Of course no flashing will occur if GUPDATE.GCD is not present, when nuvi starts ;-)

Performed the 4.2 update on my 750 last night and took it out for a 20 mile test today. The voice lag is gone, route recalculation, detour feature, and everything else worked perfectly. Now that the unit is back to the condition it was in when it came out of the box, I think I'll pass on any future updates. When you mess with perfection there can only be one result.

Just returned from a 300Km/180 Mile trip. As Bob mentions in the post above, everything seems to be back to the 'good old days' of 3.1. It's going to take some getting used to though. It has been so long that I still can't believe I can again trust the next turn instructions.

Thanks Garmin for finally taking the time to fix this mess right! Now lets not let it happen again. :)

Not happy with the new update I have a Nuvi 760 with the new 4.2 update and it seems most issues have been fixed but there is now a screen lag & sometimes it even freezes but does not lock up. Have tried a master reset to no avail.

Using British Daniel Detail set to most & 3d view.

In Australia the POI dialling still does not work

On the verge of asking / demanding a refund. Will be emailing Garmin when I get home to complain.

Not one to say the right words most of the time, two words however do come to mind.

So far 4.2 is working well for me. No "long" boot-ups, no lag, no stutter.

4.2 is MUCH better, but not perfect. There still is some lag remaining.

Jill is announcing the turn almost on top of the corner and the distances are off by 80+ feet. Jill seems to announce .2 of a mile before the turn, but it turned to .1 mile even before she finishes.

I've also seen the screen freeze others have mentioned in previous posts. Looks to me they have more work to do.

Garmin may have done all they could to get all the timings just right. It appears going by the posts that I've read (here and otherwise) they have added map redraw delays/pauses rather than have the voice stutter and in turn, also delay the prompt timing. It may be that they have indeed run into a CPU bottleneck where they now have to prioritize CPU cycles to more important things, like TTS rather than smooth, pause-free map redraws. Hopefully, they can (and will) continue to tweak things for the better.

Here's the update I promised.........
I went 532 miles around the mountains of eastern Ky with 28 stops today running two 760s side by side. One with the 4.2 update and the other with the 4.0.
The 4.2 by far out performed the 4.0 in every way except the routing END problem I'm having. If you have read any of my other posts you know what I'm talking about.
I had my laptop with me so with 200 miles to go I changed things around and updated the 4.0 to 4.2 and downgraded the 4.2 to 4.0 so now I know it's not my unit as the one I updated now loses the END point.
This is making me nUtZ.
Where can I find very detailed instructions on how to do the routing?
I thought I knew how it's supposed to be done as I've never had a problem before but maybe I'm missing something here.

Well that's a bummer about the routing not preserving your "End" point. The only instructions I've seen/used for that function are in the manual on pg 12. http://www8.garmin.com/manuals/nuvi750-GPS-Atl_OwnersManual.pdf Add the Start, then add the End, then use the green + button to add the other stops in the middle. That's the way I've always used it. Granted, I've never tried anything like 29 stops, but I've done several routes with 4 or 5 stops and it has always worked as I expected and taken me "Home" or wherever else I specified for my End point. I have a bit of running around to do this week so I'll do my best to test this some more.

BTW, I noticed two odd things today during my first drives with 4.2. First, I could not "Call Home" with my BT-paired phone. Pressing the "Call Home" button in the Phone screen just popped me back to the map screen without making the call. I was able to make calls from the Phone Book just fine. During a stop, I brought up the Home Favorite and cleared out and then re-entered the phone number. Now, it works. Weird.
Second, this afternoon I observed a VERY, VERY long startup. It stayed on the "Loading Mapps ..." screen for about 4 minutes! I waited it out and it did finally come up all the way. It worked fine during the rest of that ride. When I got home, I cycled it a few times in the garage and it seems fine - about 17 seconds to the "Agree" prompt. I'm thinking it might have been a defrag run. I checked the diag screen and it shows a last defrag with today's date. I noted the defrag count (16) and I'll be sure to go check that if I observe another long, slow startup.

That's interesting about the 'defrag'. I also noticed one long load time today but not near 4 minutes, maybe a little over a minute tops.

I used the call home phone feature last night and it worked fine, although the phone rang 'busy'. Of course my wife was on the phone when I called.

Is it my imagination or has Garmin removed the second last voice prompt before a turn? When driving towards an intersection that requires a turn, usually you get prompted "in 250m turn left at Main St:, then "in 100m turn at left at Main St", then "turn left at Main St." Now, I get the 250m turn left prompt and the final turn left at Main St but no 100m prompt.

According to the manual I'm doing it correct.
I tried the 4-5 stops thing and all worked like it should. It seems to be when I get 10 or more stops is when that's happening.

Rick, I've got several extra vehicles loaded (my 6 year old loves this feature) and a couple of Custom POI lists installed for a total of about 2500 locations. I also have a 2 GB SD card almost full with music and audio books installed in the unit. Perhaps this caused the defrag take longer on my nuvi?

RGood, AH!, now that's something I can sink my teeth into. I don't typically have that many stops in one day/route, so that might be why I haven't seen the problem. I can easily set up a test route like that and see what happens. Stay tuned.

RGood, Bingo, I think we have a bug here!
I just created a new route, Start at Home, End at Office, 10 via points, and saved it. The nuvi named it "Office from Home". So far, so good. Now, I pulled it up in Edit mode and manually reordered one point. It recalculated the route and saved it just fine. Then, I told it to Optimally Reorder Points. Houston, we have a problem! After the recalc, I pressed the Save button and now my route is named "Grandma's House from Home"! WHAT? When I go back and Edit the route again so I can see the points, "Grandma's House" is listed twice, once in the middle of the trip and again as the end point, and "Office" is GONE! So not only did the nuvi change my End point, it erased my specified End point and it duplicated another via point as the new End point. Defintitely a bug here - looks like the Optimizer code has a bug which causes it to lose track of the points it is reordering at the end of the route and it ends up losing the real End point and putting another one in its place. Like an old fashioned shell sort with a bug in it. Time to log another ticket with Garmin support I think. Sigh, anyone want to guess when 4.3 will be out?

I mentioned to Garmin last year about the routing algorithm being buggy in the 760. I would enter several POI, it would recalculated them instantly (less than 1 sec when it should take it 30 to 60 sec) and then I found many points deleted. Garmin would not acknowledge a problem. They had me exchange my unit. It is time to lay some pressure on them about this bug.

I just finished sending an email to Product.Support@garmin.com describing/reporting this problem. There shouldn't be any excuse for not investigating this since I gave them my detailed steps and it took as long to type it out (10 minutes) as it did to actually do the testing. As long as one engineer at Garmin is willing to spend 10 minutes testing their own gear, we should be able to get this moving towards a resolution.
RGood, to save me downgrading my 760 to 4.0, can you test/confirm with your two units that the problem does not occur in 4.0 but does in 4.2? Would anyone with a 3.x unit care to test a route with 10 or more vias and report their results?

The problem does NOT occur with 4.0 but if I update to 4.1 or 4.2 it WILL.
I'm forced at this point to stick with the 4.0 and accept all the other problems because routing is more important to me.
When I first discovered it was doing that I went 40 miles out of my way just to pass right by the place again later that day.

Hi all i'm new to the forum but I've been tracking these postings for two months now. Hopefully to answer storm018's question, I do have a Garmin 760 with 3.10 firmware and I'm please to report the issue with multiple routing where the END point is changed to home is NOT present with my unit. I even did optimize and recalculate route, the begin and end point are still the same.

I've purchase a 760 last month and did the registration where my unit was updated to 4.00. Of course I returned it before the time limit reached and ordered another one. It came with 2.80 and I updated to 3.20 then back to 3.10 (best one IMO). I was thinking about updating to 4.20 in order to complete registration and get the 2009 map USA but I think i'll hold off until you guys have fully test it out (very wary of NUVI updates).

For those of you who are interested I did a test on my 3.10 unit for the boot time without an SD card and here are following results: (the clock was started when the GARMIN logo appears)

Time to "Agree" Screen: 13.2 sec
Time when map fully appears: 25.6 sec

And here is the time stats with an 8gb PNY SD card with about 6gb of music. (For some reason 760 freezes if SD card is inserted when unit is on. I would recommend inserting the card when the unit is off)

Time to "Agree" Screen: 14.8 sec
Time when map fully appears: 54.2 sec

For the stuttering problem, 2.80-3.20fw does experience it occasionally (1 out of 30-40 voice instructions), however, I always have MP3 music in the background so that may take up a lot of processing from the CPU. I find 3.10 to have the least stuttering (not too noticeable) and far less crashes than others.

Lags issue I really don't think there is any but I do wish the final turn announcement were made sooner as a driver can easily miss a turn going 35mph. I've done this a couple of times when there are a lot of intersections and the screen refresh is slow to render my instant position.

Thanks for the post & the info. I do have one question for you though...where did you obtain v3.20 since you've stated that you updated to it and then back down to v3.10? v3.20 is an internal Garmin release and was never (AFAIK) released to the public. The only reason that I personally have it on one of my units is because that unit came direct from Garmin (a NIB replacement unit) with it preloaded on it.

SergZak, you're correct I never went up to 3.20 since there is no way of downloading it. 3.10 was the highest I updated it to, and I've found 3.00 to be most stable. Sorry about the confusion.

It seems I was able to register my Garmin Nuvi 760 3.00fw to obtain the 2009 Map by doing a minor tweak to this file "GarminDevice.xml" Open it under MS Word, on the 6th lne it should say "<SoftwareVersion>300</SoftwareVersion>" Change 300 (or what ever your version is) to 420 and save it (BACKUP THE ORIGINAL FILE BEFORE ATTEMPTING just in case). Garmin should allow you to register and obtain the Product Key for the map.

I have a 750 with 4.20 software, and can also confirm the routing bug. Created a route with 21 waypoints, and when it optimized the route the ending waypoint was different and some waypoints were duplicated.

It appears Garmin can't get anything right nowadays. They fix one thing and break another.

I have been following the firmware debacle closely having had nearly all the issues reported. Regarding firmware version 4.2 the following issues still remain for me;

Since 4.2 has been installed I have booted my 760 6 times, it booted fine the first 5 times, however this evening when I started it, it did the dreaded "loading maps" pause. I only left it for about 40 secs before turning it off and rebooting but it had a definite hang.

Also the major issue for me all along has been the route optimisation or optimization for my USA friends, I use routing for my job on a daily basis. I have used routing twice today, both times I have used as start and finish points "Home". As usual I input the start and finish points and then add all my vias (usually about 10-15), once the route is complete I optimise. Both times today the end point "Home" was removed and a via point (appears to be a random selection) is duplicated and substituted as the end point"

So Mr Garmin you need to keep on working to resolve these issues.

The currency converter is still messed up a bit. On mine, it doesn't matter what currency I have selected to convert to USD, when I press Update I get a screen where it says ...

1 GBP = a.aaa EUR
1 EUR = b.bbb USD (for the example of euros)

Even more bizarrely if I have, say, EUR - GBP selected, I get

1 GBP = a.aaa EUR
1 EUR = b.bbb USD
------------------
1 GBP = c.ccc GBP (!!!!!!!!!!!)
1 GBP = d.ddd USD

It appears to be "just" a cosmetic fault though, and if you enter the right figure for, say, GBP -> USD in the above screen it does at least work, but seriously, how difficult can something like this be to do right?

buellfool, I suspect that the loading issue you saw was NOT a hang, but some kind of defrag operation. I suggest waiting it out rather than forcing a reboot. I (am others that I have read about) have had some bad experiences following forced reboots. I agree that the routing bug is ugly and Garmin should hang its corporate head in shame over this 7x0 series firmware fiasco. Have you emailed or called Garmin to report it? Maybe if enough of us report it they will get it fixed in 4.3?

I purchased a 750 from QVC that came with ver. 3.2 and after registering it automatically updated to ver. 4.1 Had problems with the screen freezing up and losing the voice setting. Sometimes it would say nothing found in the voice setting block and other times that block would be totally blank. Finally gave up and placed new order with QVC for another 750. This second 750 has ver. 3.2 installed and seems to be working fine. I am not going to register this unit until I see that the bugs are fixed in their firmware upgrades. I want to thank everyone for posting the bugs found with possible fixes as Garmin's support is severely lacking. QVC stood by their guarantee and took back the original 750 and gave me a refund.

I hope Garmin gets their act together and makes this right with everyone. If not maybe a class action lawsuit is in order??

You can easily register the unit if you'd like without having the firmware update "forced" upon you. See my posts earlier in this thread for info how to do it if you're interested.

This is normal. However if someone claims they've download & installed v3.20, I'd be very skeptical to believe it due to that version never being publicly released for download to the public.

Yes, the currency converter should be an easy fix but it's not for Garmin. Garmin should do what it does "better", navigation software, not try to be financial wizards. The Nuvi 350 currency converter was never fixed.

Updated my 760 from v3.0 to 4.2. Time taken for map loading and drawing is longer than before. Other than this, the set appears to be operating normally. The other observation is that the SIRF chipset is now able to pick up weaker signal and time to satellite lockup remained fast.

Will try out navigation and report after that.

After reading this I tried the same exercise on my Nuvi 880 with FW 4.2. I had the same result with more than 10 via points. I then tried creating a new route and entering the end point twice at the end of the route. Did an optimize and all was OK. Not perfect but a possible work around.

Now, I pulled it up in Edit mode and manually reordered one point. It recalculated the route and saved it just fine. Then, I told it to Optimally Reorder Points. Houston, we have a problem! After the recalc, I pressed the Save button and now my route is named "Grandma's House from Home"! WHAT? When I go back and Edit the route again so I can see the points, "Grandma's House" is listed twice, once in the middle of the trip and again as the end point, and "Office" is GONE! So not only did the nuvi change my End point, it erased my specified End point and it duplicated another via point as the new End point. Defintitely a bug here ...

I did my own test of the routing function on a 760 and found that it works up to 6 points (start, end and 4 via points). After that you get the end point removed and a duplicate of one of another via point. I'll contact Garmin as well.

Thomcli, did you mean to type "my Nuvi 780"? I'm guessing you did since I believe the current version for the 800 series is 3.2. Anyway, that is a very interesting idea and I'm going to try it out. One thing I noticed last night experimenting with this is that not only does the "Optimally Reorder Points" wipe out my desired End point and duplicate another stop, but the order it came up with didn't make much sense either. The list of stops it came up with looked like it took all of my points, threw away my desired End point, made a copy of another point to make the via count match again, and then spit the list out in random shuffled order. My cat could have done as good a job "Optimizing" the route. When you tested it with the double End point, did the results make sense?

Wow! I'm surprised (and sad for you) that your 880 has the same problem. I guess the code base for 8x0 series must be pretty closely related to the 7x0 series if this ugly bug appears across both families. So much for my thought of returning my 760 and buying a 880 to get to a more reliable platform. I wonder if the new 7x5T units have the same problem. Anyone with a 7x5T care to test and report?

To be honest I have never had an occasion to create a route with via points along the way. My normal usage of the GPS is just a starting point and an ending point. But after reading the above posts regarding the multiple via points I tried it out. First, I used seven via points between my start and end points. After allowing my 750 to "optimally reorder points" I found that my end point was also removed and another via point substituted. Second, I created a route with four via points. After optimally reordering points, the resulting route was just as it should be.

I have sent an e-mail to Garmin regarding this bug even though, for me, it won't have any real effect.

Today, Oct 16, Garmin responded to my e-mail as follows:

I found a bug in 4.2 that was also in 4.1, don't know about 3.x
On the "where am I" screen, there is a "nearest intersection" item.
On my 770 the displayed intersection is about 1 mile from me, with dozens of intersections between my location and the displayed intersection. It is so far off that it would be useless for any emergency response.

My wifes Magellan 1412, has the nearest intersections correct.

Yes I did.
I only noticed it recently and did not go driving around to see how bad/useless the "nearest intersection" is. I plan to do that in the next few days.

Cheez, my wifes Magellan 1412 (at half the cost) looks better each time I run into one of these bugs.
The first "problem" was the audio lag that everyone complained about in v4.1.
I'll see how the 4.2 update fixed it when I take it out tomorrow.

This AM when I turned on my 760 (after having created a route the evening before) I called up the route and pressed GO my route was changed from 200 odd kilometres to 2.4 kilometres, no idea what happened, I re-optimised and it was OK (after removing the duplicated entry and reentering my correct endpoint). I also lost my TTS voice, and as was happening before 4.2 had to restart the unit before I was able to re-select my TTS voice.

I too notice the nearest intersection wrong and I'm using 3.00SW. Nearest Exit on freeway is correct but when traveling inside the city it gives the nearest crossroad being about .5 miles away and it's usually the major roads. Have never experience losing TTS voice selection tho.

@ buellfool:

Did you by any chance interrupt the boot process because it was taking a long time? I found (under 4.0) that doing this would trigger the TTS problem. My best guess (based in large part on others' observations here) is that occasional longer bootups are part of the defrag process and interrupting that can have bad consequences.

danham - yes I did. OK I will cease and desist in this practice. However I am mystified, why prior to 4.0 I never had a long boot process/defrag issue? Also I would have thought that if a defrag was occuring then surely it would say so rather than saying loading maps. So far as I can see we are now at 4.2 and there are still major issues yet to be resolved.

I suspect Garmin purposely omitted the defrag message as part of its effort to dumb down the nuvis. In any case, interrupting a defrag on any storage device is a bad idea.

With 4.0 the problem was really bad, but on my x-country trip I quickly learned not to interrupt the bootup unless I wanted to risk navigation weirdness and the TTS problem. Since 4.2 I haven't seen any long boot times, so maybe the process is working better, but in your case perhaps needed one good defrag before subsequent ones could be done quickly? Just guessing.

I am not experiencing any major issues with 4.2 yet, so can't comment on that aspect.

I found the occasional long boot time happens each time you do something that makes the file current.gpx grow like building a long route or navigating (create triplog). When you switch off the 760 you will have a long boot time the next time it is switched on. It will then go back to the usual short boot time the following times you switch it on until you again do something that grows current.gpx.
I tried this:
Create a route from Geneva to Barcelona
Switch off
Switch on => boot in 82 seconds
Switch off
Switch on => boot in 19 seconds (normal)
Create a route from Barcelona to Geneva (I now have two routes)
The first boot time after off-on is now 109 seconds.

It looks like the more data you have in current.gpx the longer the boot time when it grows. I have seen more than 3 minutes

Nice diagnosis on the defrag process, lbuch! I have suspected something like that from my observations, but I never went as far as you did to try to analyze it. I also concur with Danham about bad things happening if you force a reboot during a defrag. Better to just wait it out.

@ lbuch:

Excellent! Thank you.

This explains a bunch of things. While running 4.0 on my trip, I was using lots of complex routes. After I got home I updated to 4.2 and have not really tested it that much nor have I used complex routes.

Assuming that the defrag theory is correct, you would think Garmin would notify owners about this new process.

People are going to think their unit is defective when it takes over a minute to boot up.

Agreed. It would be a good idea for them to add a watchdog timer to the startup and if it takes longer than nominal, perhaps 20 seconds, they should display some kind of "Please wait ..." animated message to let the user know it isn't "hung".

Also, if the nuvi only has a slight residual charge left in its battery, I've found that it can come on for less than a minute when switched on and suddenly go off when the residual charge is spent. This may also interrupt a defrag on boot, unless the code checks the battery state before starting a defrag.

Unless I missed something while reviewing this thread, it appears that none of the reports of long boot-up times were associated with the nuvi 750. I have cycled my 750 several times since installing ver 4.2, as well as all the other firmware versions, and have not experienced the problem. The significant difference between all these units is that the 750 does not come with bluetooth wireless. Perhaps the bluetooth feature was not appropriately addressed in this latest firmware release. Just thinking out loud.

Notlost, In one word ... YES! I definitely think you should stick with 3.1 for now. I so wish I could task a spin in a DeLorean and go back in time about 45 days when my nuvi 760 was running 3.10 {sigh}. This whole 4.x thing has been a very negative experience for me so far.

I agree with storm018.
I can't even get Garmin to respond to me on this latest routing end point bug.

It would be better if Garmin move the defrag to run AFTER turned off the nuvi.
That way it can run when we don't need to use it. And we don't have to wait for it to complete.

Defrag or no defrag, it is unsatisfactory for a GPS unit to take 3 minutes to boot up. I used to be able to get in my truck start it, and long before I got to the end of the drive (350M)I could press GO for my route. Now I sit at the end of the drive and wait. I still maintain that prior to 4.0 I had no occurance ever of a slow boot up.

Why would you need to DEFRAG a SSD? It won't improve seek times, there are no heads to move. It's a wasted effort. I think they may be building new file indexes.

After installing 4.2, I pressed the Media Player icon and then the Source icon. The Nuvi instantly crashed (screen blacked out and shut off). After rebooting, accessing Media Player has since worked fine. Can someone confirm this error (make sure you have not accessed Media Player since installing 4.2)?

Thanks,

Buelfool, I hear you, but as Danham, lbuch, and I have tried to explain (based on observations, since none of us are Garmin programmers), the unit doesn't do it every time it starts up or even often, unless you are routinely working with routes. The normal startup time is <19 seconds. That's what I have seen with my 760 since 4.2 except for ONE startup the on the first day I used it after the upgrade, which I waited out.

Steveru621, I'm not a programmer, but I recall the defrag process being discussed in the forums in the past. I think it defrags objects in memory to free up handles/pointers, not for the same reason you would defrag a mechanical storage device. At any rate, the unit clearly performs and tracks defrag activity which you can see for yourself in the diag screen (touch and hold on the speed gauge in the Trip Info screen).

HPatlik, I haven't seen this happen. I did have one weird thing happen on my 760 after the 4.2 install (the can't "Call Home" thing I mentioned a few pages back in this thread). I have had thoughts that I should really do a master reset under 4.2 to get rid of any residual badness that 4.0 and 4.1 left behind. Now that we have discovered the routing problem, I think 4.3 isn't too far off, so I'll probably wait until then unless I see some other weirdness.

A master rebot did restore the fast bootup times and I think it is critical that you do not shut the unit while the map loads. So far, after the master reboot it has been behavin'. They even fixed that sputtering speech issue with the GMT traffic when you displayed the listing of traffic problems.

Well said.

Another observation is that these units appear to be operating right at the hairy edge of processor capacity, so just as de-fragging a mechanical storage device speeds up seek times, so would ability to find needed code in SS memory on the fly without consulting lots of complex lookup tables which keep track of stray bits of code stored in fragments.

I sent the following message to Garmin's Technical manager:


Title: Nuvi 750 V4.2 is unacceptable!

In my opinion, there is a major hardware problem with this Nuvi 750 GPS unit. There is no doubt in my mind that the CPU or other hardware components are not able to handle all that V4.2 software requires. Consequently, the CPU demands are being parsed (command priorities have been set). Thereby, causing all of the following problems:

1. There are fewer voice prompts given - especially, when approaching turns.
2. The car and mileages hesitate when voice prompts are given. When approaching turns, Jill’s voice causes the mileage indication to delay and then it jumps .1 of a mile.
3. When actually making a turn, the mileage indicator is still showing 8 to 150 feet to go.
4. After making the turns or changing directions, the refresh hesitates and then is slow to show new location.
5. Different routes are being given to familiar routes previously given on my Garmin 340 GPS unit.
6. When you go off route, major delays occur both with the recalculation notification and the refreshing of new route.
7. During the simulation of a programmed route, there are erratic pauses and stops and catch-up mileage notifications – major parsing takes place because of all of the software commands being given in short period of time.
8. When adding a new location to an existing route, the calculation just adds the new location the end of the route. You have to Optimally Reorder Points to incorporate the new location.
9. Under My Location, the nearest location is 2 miles from my home. The closest major intersection is only 3/4 mile from my home.

All of the above problems point out the fact that the V4.2 software upgrade is a cobbled together fix that is unacceptable. It is not what I paid for when I ordered my Nuvi 750 from QVC. This is my third Garmin GPS and I know how they are supposed to work. This unit is not working properly; it is only barely functioning to approximate how it should work.

I purchased my Nuvi 750 five weeks ago. Three weeks ago and again two weeks ago I contacted Garim Technical and asked them specifically whether the V4.1 problems could be fixed with a software upgrade. Both Garmin technical contact personnel stated, with great confidence, that yes these problems would be resolved with software upgrades. On that basis, I did not return my Nuvi 750 to QVC. Now, I can not return my Nuvi 750, as the one month return policy has expired.

Once again, please advise if indeed these problems can be fixed with a software update.

I have not heard from them!

Now that my 760 seems to be back to normal (sort off) I am reluctant to make any changes but wonder about doing a re-set.
What info is lost when this happens ie is it just my favoirites and can I specifically back them up before a reset? I dont want to copy over the whole file system and then copy it back in case I introduce any new errors.

Modern flash cards and associated hardware and drivers all include a great deal of optimization which works much better when the access is contiguous. So file system fragmentation does indeed involve a significant performance hit. There are too many variables to quantify this in any meaningful way but, as I said, it can be significant.

As an aside, this new nuvi 750 owner is reasonably happy with the 4.2 firmware although that multi-point routing bug is something of a humdinger and needs to get fixed pronto!

So much for my thought of returning my 760 and buying a 880 to get to a more reliable platform. I wonder if the new 7x5T units have the same problem. Anyone with a 7x5T care to test and report?



I've just tried creating a route with 15 via points on 765T with firmware 2.20 and do the optimally reordering. Everything works as intended, no duplicate or missing points and my end point did not change.

If you want to save just your favorites you simply need to save the contents of the Nuvi's Garmin/GPX directory. A reset will reset user data which is basically the various settings that you made when you turned the Nuvi on for the first time.

You should always insure you have a full backup of your Nuvi in any event but simply doing a reset shouldn't delete any non-recoverable data. Just in case something should be deleted you can recover it from your backup.

Judging from the numerous post. 4.2 corrected some of the issue. But not all. I don't see a compelling reason to upgrade from 3.1 to 4.2. No added fixes. They are just trying to repair issues they broke in previous releases.

Staying with 3.1

Thanks Poppap! I saw you in another thread with your new 765T and I was hoping you'd chime in here. That's great news that the problem does not exist in the new series. Hopefully Garmin can quickly resolve the problem in the 7x0 series units with a software update. I'm lurking in the 7x5 related threads and thinking about upgrading once they become a little more available.

Routing: this feature worked great until recently. I can only get it to work correctly if I enter the end point twice.

I just opened the phone book and entered 10 consecutive addresses with a favorite for the start and home for the end. I followed the same procedure..next...save...select route....optimally reorder points. It drops the end point, duplicates another point, inserts it to keep the via point count the same.

If I double enter the end point it works fine. Really screwy!

I wish Garmin would just give us a way to downgrade back to 3.1 until they can sort this whole mess out. It's been going on for 2 months now. Garmin should be paying us to do Q/A for them.

It looks at tho I'm in the minority, at least of those posting here. I have no outstanding issues whatsoever after 4.2. My routes work as they should, no problem following the voice prompts, even in dense Orlando traffic. IF there is any delay, I haven't noticed it in normal use. Routes may be different than what the SteetPilots give, but that's always been so. The algorythm has been tweaked as least twice that I know of. Nearest intersection has been hit or miss as long as I've had my nuvi, certainly no result of any of the firmware upgrades. IMO, 4.2 has corrected any issues introduced with previous 4x firmware. All in all, Garmin did what I expected with 4.2. Did it correct every issue with the 7x0's? No. But it sure looks like they corrected the new issues they created.

Just got through talking to Cust Supt.
They don't know about the incorrect "nearest intersection" on the "where am I" screen. And that the reported intersection is so far away from where I am, and with dozens of intersections between me and the "nearest intersection" that it is useless to give to the police or cab as a reference.
I told him that several people on the internet reported it as well, so it isn't a one-of problem.
He said that he will report it to development...sigh

The routing algorithm has never worked correctly since the 7x0 series came out. They now enough user input information to put this bug to rest once and for all. But they should insert one more voice prompt for turns that was present up until v4.1. They have revised the last prompt so that is speaks too close to the intersection to make a turn safely.

Just in....

I reported the routing issue and here is the asinine response I got (please disregard their "advice", it will not work). The front line "tech" support Garmin hires are mostly useless:

Thank you for contacting Garmin International.
I will be happy to help you with this. This sounds like an issue
updating with our WebUpdater will solve.
To update your system software (firmware), download the web updater.
http://www8.garmin.com/products/webupdater/howtoinstall.jsp
After this program installs, your unit will need to be attached to the
computer via the USB cable. The WebUpdater will attempt to update itself
and then search for your unit . The program should then recognize the
unit and you will just need to click next and follow the instructions to
update your unit. When the system?s firmware is updated, you will have
the option to update additional software that is present on your unit.
It is best to look at this list as well and check any firmware or GPS
update that are available on this page. Also, if you see the voice file
that you use on your unit, you will want to choose that as well.

Hmmm, as a new 750 user I can't speak for earlier versions but I can see that the nearest intersection is way off. Furthermore, my Nuvi seems to know it came up with the wrong answer because it constantly tries to recompute a better one. I just watched the hourglass spinning while it made a dozen or more attempts, producing the same wrong answer each time. Something is clearly broken.

Since I can reproduce this instantly at my home, I'll send it in to Garmin tomorrow. The more folks that complain, the sooner this will make it onto the developer and management radar screens.

Does attaching the Nuvi to a PC and running Webupdater show a GPS firmware version available? If so let webupdater download and install it for you. The GPS firmware is listed with other 'Extras' after any software updates the units may require.

I just thought I would add my 2 cents worth following a recent upgrade of my Nuvi 760 from 3.10 to 4.20. I purchased the Nuvi in Australia and am now using it in Europe (mainly Switzerland).

I've posted the text of my e-mail to Garmin below which explains things.

I'd be interest to know if anyone else has experienced similar problems.


"After recently upgrading my Nuvi 760 to firmware 4.20 I have experienced a number of issues. I was previously running version 3.10.

In the first hour of the first drive using the new firmware, the GPS performed OK except that I noticed the British English voice (we don't use TTS) paused noticeably between certain words. For example there was a noticeable pause between the announcement "three point" [long pause] "one kilometres". I ignored this and kept on driving, thinking that the GPS would stop doing it after a while. It did not.

Then, the Garmin's voice completely dropped out and my fiance had to announce the turns for me. Then we got an error message from the Garmin to the effect that it could not find the audio speech file.

Then things really started going strange. The on-screen map disappeared and it was all grey where the map should be. The header and footer bars (eg the Arival, Menu and Turn sections) were all still there, but no map. Shortly thereafter the Garmin reported "Unable to Calculate Route: No roads near destination".

It was very hard to then get the GPS to reset. I tried holding the power button down and it wouldn't budge. After a while, it reset and came back online. However, before coming good it crashed a number of times on the "Loading Maps..." screen. Incidentally, I purchased the nuvi in Australia and am using City Navigator Europe 2008 maps (all 2.3gb) on a 4gb Sandisk SDHC card.

On the return journey that same day, the GPs started to lag really badly to the point where I was missing turns. This has never happened before on any firmware version.

The next day I performed a master reset (using the bottom right hand corner etc).

On the second drive with the new firmware and after a master reset, the GPS worked normally (no lag at all) for the first 20 minutes or so. Then, the sound lag issue came back and the navigational lag was still there and I started missing turns again.

Shortly thereafter, the map also disappeared completely from the screen again.

Amongst all the confusion the MP3 player also stopped working. When I went back to the Media Player Screen and selected a new song or group of songs, it just returned to the media player screen with the words "Browse" - it completely ignored the fact that I was trying to select and play a new song/songs.

I came home and then tried to downgrade back to version 3.10 - obviously this is not allowed as the downgrade did not take.

Thinking it may be a problem with my European Maps I have now formatted my 4GB SDHC card and transferred a fresh set of maps to the card. I have not tested this yet, but I am currently simulating the route that crashed yesterday to see if the map drops out again. During the simulation – everything seemed OK. However, this is no guarantee that it will work fine on the road.

I have checked your support area on the Garmin website and done some research on various GPS forums (GPSpassion etc). I have found no solution to my problem.

I checked the last defrag date which was 17 Oct 2008 which was the day I updated to v4.20. Could the defrag have thrown it off and caused the lag and constant crashes?

Anyway, I would now like to know what can be done about my Garmin? Should I wait for version 4.30? Is it possible to downgrade to 4.00 (I've only tried downgrading to 3.10 and this did not work). Has anyone else experienced such problems?"

You can easely downgrade to 4.00, but it will not help you.

Hi Jotne - why not? Will it exhibit the same basic problems?

Thanks

Adrian

Adrian,

Per our FAQ, please do not quote a message if it is directly above. thanks.

FW 4.2 is considered by most of us to be a big improvement over 4.0, which had all the problems you describe.

Even with 4.2, interrupting a "long" bootup (which I believe is caused by the defrag routine) can trigger these problems, so be sure to let it do its thing without touching the power switch.

Thanks danham - will do.

I just thought others should be aware that if you're upgrading from 3.10, you may start to experience these problems.

I've never had any problem whatsoever with my Garmin 760 (apart from a gripe with the playlist shuffle routine).

Also, I did let the Garmin do its thing when I first rebooted it following the update - and it worked fine. It was only on subsequent power-ups that it starting take its time to "Load Maps" - which is when I had assumed it had crashed. This is why I interrupted it.

The only thing that changed when I went back to 4.0 on one of my 760s was the ability to use my routing without flaws. All the other flaws are still there but it's something I have to live with in order to do my job at this time.

Starting Media player stops the current route. Garmin 760 with 4.20

On a recent trip I noticed that when I started the media player the the current route was stopped, as if I pushed the stop button.

The scenario was as follows

Unit not in "safe mode"
Driving on a highway
Using FM transmitter
Selected Media player
Started player
Unit stops current route so I had to reselect route

I use the logging facility for trip reporting so this is a bit of a pain

I repeated this a couple of time and issue is totally repeatable.

can anyone else comment on this

Just completed a 300Km/180 mile trip the other day with 4.2 installed and used my 760 as you describe. My unit never stopped the calculated route at any point when starting or stopping the media player.

@ TraderBob:

This is one of the symptoms mine showed while running 4.0, BUT ...

It only happened if I had interrupted a "long boot," and it does not seem to be happening under 4.2.

I had not really put the MP3 issue and the route shutdown together until I saw your post (thank you), but now that I see it, this is part of the trouble I had on my cross-country trip and so I stopped using the MP3 player.

Just out of curiosity, how many songs do you have and are they on an SD card? I had a lot (around 1000 IIRC) and that was also slowing down the bootup. I've since erased that card as I'm no longer in a rental truck (thank goodness) and don't need to use the MP3 function.

In reply I am using a 2G SD card full of music, I have not tested with the music stored on the Garmin.

I normally use the radio and it was when I was driving in a low reception area that I discovered the issue
