Just had the weirdest thing with my F900BT. Was driving on I-81 in maryland about 2 hours from home and randomly the GPS said I was going 90123090mph then it kept increasing in speed and all of a sudden the unit rebooted. Then it was stuck in a vicious reboot cycle for a good 45 minutes after we stopped for dinner. I had a SD card with test mode files on it I was trying to get loaded but never got that to start. On the way home the unit eventually booted up normally and let us at least listen to the radio. That was a blessing, try driving 150 miles home in a turbo rsx, solid motor mounts, 3" e
