My 765t died tonight...anyone else?

It seems others have experienced the same issue this evening, I have found, after frantically searching for a fix for mine on this and the gpspassion forum. My 765t is toast (Second in five months)!!! I used it earlier today, and worked fine. This evening I have it inside...just running off battery (which had plenty of juice)... was entering in addresses to save as favorites for an upcoming trip on Wed., when I got a message pop-up and say updating GPS firmware..then update completed. It did this 5 or so times, then shutoff. I cannot power it on..I cannot hard-reset it...I plugged it into my beanbag mount in the truck, and normally it turns on automatically, but nothing!! FYI..I use the MSN receiver power adapter. I have had the latest firmware and the latest maps since they were released. I did not update the recent voice updates yet. This is a referb unit, because my first one died also. I am getting very frustrated and worried, because the referbs are only covered under warranty until the original 1 year warranty expires. This means another referb, and only 7 month warranty!! Calling Garmin in the morning.

If your unit still powers on and connects to the PC, I'd highly recommend doing the following until some answer or solution is provided by Garmin or otherwise.
Rename the GPS chipset update file on the nuvi temporarily to something else. If the update file is not seen by the nuvi, perhaps no update will try to take place. The files are:
x:/Garmin/RemoteSW/006B073300.GCD
x:/Garmin/RemoteSW/006B073300.bin
Rename the two to something the nuvi won't be looking for such as:
006B073300.GCD.disabled
006B073300.bin.disabled
After doing so & when you run WebUpdater, it will state that a "GPS Chipset Type M" update is available...just ignore it. Maybe this will prevent the problem from bricking more 7x5 series units.
When the issue has cleared and it seems safe to do so, just rename them back to their original filenames.
I did have all the latest updates for the unit AND do use the GDB50 / MSN Direct.
About an hour later I got back into my car and the 765T would not power up. I have spent most of the evening trying to get the 765T to power up. I have plugged it into my computer via the USB cable. I have plugged it into the AC charger. I have held the on switch in the on position numerous times for 10 seconds, 15 seconds, 60 seconds. I've tried turning it on while pressing on the lower right corner of the screen. Nothing has worked.
The 765T will not power on.
Coincidence? I don't think so.
P.S. I do not have MSN.
I'd advise all those affected to do the same.
The question is, is the trigger the date, e.g. June 22, 2009? Or is the trigger the number of days since the firmware update was installed? Or something else? What is the common denominator?
I think Garmin has got to take a look at the origin of the problem and fix it, and not just replace units.
In any case, I think Garmin has a big problem on their hands, and replacing the 765T may not solve the problem for long. Update the firmware of your new replacement 765T and it dies again? Let's hope not.
I hope I'm wrong about all of this.
I don't think so many 765Ts failing in the same way at about the same time is just a random event. Too much coincidence.
Let's hope Garmin steps up and tells us what's going on!
I can only imagine how many other 765T owners had their units fail in the same way and we're not hearing about it because they don't know about this forum.
I'm waiting to hear back from Garmin.
When I left to work this morning @ 1am, all was fine. On the way to work (8 minute drive), satellite reception took a dump after about 4 minutes and my position froze. Satellite reception was zippo. I unplugged the GTM (did not power down the unit) and let the unit shut down due to loss of external power. I plugged the GTM back in and all was well the rest of the way in to work.
This *seems* to indicate that movement is required for this bomb to hit. Remember, I have renamed the GPS update files as above and did NOT receive the "Updating GPS firmware" message. I will see what happens on the way home. If it happens again, my next course of action will be to backdate the firmware to v2.50 & see it it resolves the issue.
Garmin has a BIG problem on their hands with this stinky time-bomb...
Since you seemed to have dodged the bullet, and can still use your 765T, please let us know what you find out.
Mine is dead!

Obviously this is a Garmin issue. Very aggravating. Especially if we all have to send our units back in. I've been a loyal Garmin owner for over 10 years and this is my first gripe with them.
My guess is this has to do with the date, June 22 and that every 765T that has the latest firmware will experience the problem.
It will be interesting to see how this unfolds as the day progresses.
Anyone out there who didn't upgrade to the latest firmware experiencing the problem?
SergZak. Please let us know what happens when you downgrade your firmware to v2.50.
Let's hope Garmin gets a handle on this fast!

Have not powered it on since....
Anything I can do to help debug before I power mine on and try to make mine fail :) :?:
fyi, I hadn't updated the firmware since a while back.....
but 2 or 3 days ago it did say a flemish voice needed to be updated.... IIRC :?:
fingers crossed
so far, so good.... seemed to plan a route, but have to do some real work, will test more later
Oh well, I suppose I'll take the story elsewhere. Just thought I might be able to help!
Edit: Links were being added; the story had to be revised and our cache takes a few minutes to refresh thanks to traffic. Anyway, sorry for the trouble. I suppose I'll come back if I hear anything else on the issue you guys might appreciate.

I went back to the car and although my 785T powered up OK, the GPS signal bars then all disappeard and the GPS software version went to 0.00. Then the touchscreen locked up tight (still getting 'GPS Update Complete' messages) and all I could do was power it off; then nothing, would not power back on using any power source.
I brought into into my lab which happens to also have a GPS repeater and I for whatever reason was able to get it to power back on and connected to my laptop. I now have favorites backed up and renamed the two files above.
I am on hold with Garmin Tech support and was about 30 minutes wait time when I first dialed.

Waiting for him to check again with software engineer...
Told him about this thread....
Support person sounded a little stressed.
He thinks that those with units that won't power on will need to exchange their units with the fix-software one they figure out what's wrong.
Changing the unit won't help right now because he thinks the couple of hundred units ready to ship out as exchanges probably already have the 3.4 software on them and might exhibit the same problem (since 3.4 was released months ago).
Right now all we can do is sit-tight for the engineers to figure out wha't wrong and release an updated software version for those than can still power on their units.
He made a note that I've offered to test any update since I can still connect to the webupdater but have the issue. He has my contact info now as well.
He didn't seem interested in the GPS update files ZargZak mentioned above. I am going to rename those as ZargZak recommends for now and see if the messages goes away and wait for an update.
Should keep them renamed for now anyway?
Garmin really expects the customer to foot the shipping bill only to receive a refurbished unit? I for one think this is completely unacceptable as my unit was in pristine condition until last night when it bricked. I believe we should be given new devices or refunded for the purchase price. If I wanted a refurbished unit I would have bought one to begin with...
*angry fist* at Garmin, will be calling their tech support as soon as I get off work.
is that on all 765t's ?
how can we chk ?
Hold your finger on the battery icon until the diagnostics screen comes up. Go to the screen that Has Version information on the top. Hit the start test button, then hit the MOR button. Scroll down till you see your chip.
but I can't pick out the chip on my 765 :(
I needed to use my 785T on Thursday to take a trip to Washington, DC with my family. Will I not be effected by this problem if I unplug the MSN cable from the suction mount and just let it run off the battery?
i installed the newest software AND the chipset update, and all is well here
this morning backed up everything via windows explorer,
let it run on battery and calculated a route....
then connected to 12v to 110V wall outlet and calculated another route...
still seems ok thus far, but I haven't taken it for a ride yet....
curious....
I did check and I have the latest software 3.4
I am also running version 3.40
I am correct in saying that my unit will not do any updates unless I plug it into my usb and use webupdater or plug it into my msn cable in the car? The unit does not receive ota updates, correct?
My Diag screen reports:
3.40 nuvi 755 V8 4GB P1 S3 330MHz
And the Start Test > More list reveals a MediaTek chipset.
It seems all the planets are aligned for mine to brick as well... but so far, everything seems to be working (fingers crossed).
To those of you who experienced this issue: was the device in use for a particular period of time before it was first experienced?
Steve
SW Ver 3.40 nuvi 785 V7 4GB P1 S2 330MHz
The executives at Garmin right about now should be working on spreadsheets to figure out how much it will cost to send everyone who has a defective unit a brand new unit at no charge so as to turn those customers into happy customers and to avoid very bad publicity and its costs, compared to the cost of defending multiple lawsuits and possible class action lawsuits.
Let's give them some time (72 hours, one week?) and see what each group at Garmin comes up with.
