I haven't noticed any problem with a new Nuvi 760 just upgraded. I've done a few tests routes of about 20 mins and its seems ok so far.

I have the nuvi 760 as well. I upgraded a couple of days ago to 3.10 and today i read your posts, so i did a test by simulating a route and left it for around 15mins and it worked fine Confused

Hmmm... Looks like i'll be upgrading again then.... Perhaps a duff upgrade.

Re-upgraded to 3.10 and reset user data for good measure. Tried route again and still switches off / crashes. Noticed that when it does it it still displays the last image very faintly on the screen. I've done the same route several times now and it always crashes at the same point. Then i tried a new route and it crashed before it even finished the first instruction!! Going to try and work out if it's something with the map by routing in the opposite direction.

I'll also post the routes I'm running here so others can try the same routes if they wish to test their units. If the problem is specific to certain junctions, co-ords, instructions etc it should be obvious if we all get the same problems with the same routes.....

It's currently running a route from Leicester to Newcastle. 4+ minutes and no problems so far....

Can some try the following with 3.10 firmware? Takes less than a minute...

1 Upland Road, SM2 5HW to 236 Carshalton Road, SM1 4SA - crashes at a point after crossing second railway bridge when you get to junction of Kings Lane and Weirhurst Gardens. Doesn't crash when travelling in opposite direction...

On one occassion, crashed when i try to set my location as 1 Upland Road, SM2 5HW. If i do it manually by pointing on the map it's ok, but entering that address and then Show Map, the Set Location = Crash. Second atempt worked ok....

Ok, done that. I set up a new route to go from and to those places and then ran it through as a simulation. Did it a couple of times with no problems.

Using a 760 with 3.10

Also set the start location (using address, show map, etc.) and then went to end address. still no problems.

Hi,

Not posted before so here goes....I am having the same problem with the upgrade with the nuvi either freezing or turning itself off.

Regarding the roll back to 3.00 firmware on the link given there is no 3.00 exe for the NUVI 710T. I take it I cannot use the firmware for, say, the 750T as it's not generic.

Also I have run some routes on the simulator and it seems to work fine when I unload the POI's such as ATM's, Accom. etc and just have the speed camera database loaded in.

anyway off out today so shall give it a proper run and see it the unit works properly.

Actually the firmware is designed for the 7xx Series according to the first screen when you run it so the 760 or 770 should work. The firmware for the 760 and the 770 are identical (MD5 check)

However some US models seem to have slightly differernt Firmwares.

I have the 3.00 7xx firmware if you want it.

Are you saying the crashes occur when you have POIs installed, but when you don't? Or at least over a certain number of POIs....

Well I ran Paulb2005's route with no problem but today I went out and started having problems. The unit will freeze when under power or just switch off when on internal battery.

I had these problems in two distinct geographical areas and my gut feeling is that it may have something to do with a number of POIs being nearby. Just a guess but that might also explain my not having a problem with PaulB2005's route.

Anyway, I have reverted to version 3.00 and will await Garmin's pleasure.

Got also the automatic shut off when running on batteries. I am running 3.10 as well.

I thought it was because I was doing some funny stuff with my VPM voice files, but nothing that could explain this. I tried 3 times and it shut off exactly at the same place.

Maybe I'll go back to 3.00 as well.
