Hi, This all happened yesterday and I left it charging overnight with no sucess. Tried this morning at 5am before I left for work and it was still frozen.

Yes, its the PC Icon on the screen of the Nuvi, visable at all times; no change whether I plug it into the PC, AC Adapter or Car cradle.

Tried it on the car charger with no sucess.

Tried 3 differant USB cables.

Best option to let it run down and switch off by itself, hopefully I'll be able to get to preboot and Hard Reset.

Its a pity I dont have the tiny Torx socket to open the case up, then I cound just remove and reinstall the battery, and it would reboot.

I'll let you know what happens.
