Full Story and now it is working fine.
Was route maped to one location then on the MAPs screen told it to go to a geocache. It started calculating then it just went dead. Had it plugged to garmin car addator for power and good batteries. Every time I started it up again it would load up to the main screen then 2 seconds later just shut off.
I tried computer cord and new batteries but all ways the same thing. Long story short I took the maps SD card out and started it up again. It stopped and said it could not calculate roads, I pressed OK and it is working fine now. I have now added the Roads SD back and it is still good.
