Freezing problem on 760 after upgrade to software v3.10

I have had my 760 for 3 months and had no problems with it. Yesterday, 2/8/08 I upgraded the software to v3.10 and since then I have had problem with the screen freezing, requiring power off to overcome it. Is this a common problem and is there a fix available?

Thank you Phil,

The logic of a previous version overcoming a later glitch quite defeats me.
I was quite neutral about it until the other day.

Also discussed here

It one of the things i'm writing to Garmin about later this week - i've finally had enough of my 760 and wish i hdn't bought it. I loved my i3 but the maps and software on the 760 is appalling.

Well I've just drafted a 4 and a bit page letter to Garmins Customer Support. Basically comparing the 2 years i owned an i3 Laughing

to the 5 months I've owned the 760T Mad

.

It includes how i only found 3-4 map errors on the i3 (v8 maps) but within 2 weeks of owning the 760T I'd been routed down one way streets the wrong way several times, through gated private communities with no through access and into a pub car park and out through a 20+ year old wall...... Shocked

Also complained that with the TMC signal being so weak was a wire antenna good enough? I know the signal is not their fault but if they sell an antenna it must be fit for the job.....

Also that Garmin support takes ages to answer a question, they ask for details that were provided in the previous message further down the page, ignores the contents of all previous correspondence and when stumped suggests a "Master Reset", or installing the latest firmware which I've already told them is installed.

Oh and the time they started sending me the responses to someone else's tickets.

Plus the problems with the Bluetooth "Phone Home" bug and the "Phone Disconnected" bug

But really the final straw was the Firmware 3.10 bug.......

So we'll see what they have to say.....

I've been very defencive of Garmin in the past over these matters...... No more.

I'm also getting the screen freeze problem on my 760T following the upgrade to V3.10 firmware, but interestingly ONLY when the map screen is displayed when NOT routing. I have done two or three long routes in the last few days without a single screen freeze, but if not routing the map screen freezes between 2 and 10 minutes every time.

No screen freezes happen if I have a non-map screen displayed.

I've also noticed the freeze happens only when the screen is zoomed in (below 30mph) and never seems to happen when zoomed out (above 60mph). I guess this indicates the fault is either with the auto-zoom function or, as previously speculated, with the POI which are only displayed when zoomed in.

At the moment I am resisting the temptation to downgrade to V3.00 in the hope that Garmin will roll out a fix in the near future...

Well I've just re-upgraded to Firmware 3.10 for the xth time and now none of the usual suspect routes is causing a problem....

(and again literally as i typed that it switched off......)

Back to 3.00......

By the way has any one else reported this problem to Garmin at all?

I find this problem is very different to the problem with the i3 and Firmwares above 2.70. Confused

The problem I had with the i3 is that it would preform ok until i got to certain points on the map when the main part of the screen displaying the map would freeze. The i3 would continue to give audio directions and the information at the top (next turn or next road name) and bottom of the screen (ETA and Distance to turn, or Speed and Compass Heading) would continue to update accurately. A minute or 3 down the road and the map would snap back to life again.

With the 760T the freeze is a total lock of the unit when on power. On battery it freezes and the back light goes out - you can see the last image on screen very fiently....
