Last night i noticed my GPS will not work on my deck. I turned off the power to the deck, when i started up my truck again my deck will boot up the poineer screen and reboot.

I held down the menu and map button, the deck said to hold for reset. I did that and after a few seconds the deck turned off.

Any suggestions what is wrong with the deck? or what i can try?

I have the 910

I have the exact same problem. No problem for first 4 months, then dead GPS and I'm in reboot hell. Comes online after between 15 and 60 reboots, depending on my luck. I'm not happy I can't find a phone number on their website to actually talk to someone to find out how to send the unit out for repair either. I found this number 1-800-421-1404 in a google search. I'm on hold now, hopefully they can help.
