I won't go into all the details of the Garmin Support, but I will say that it took four hours from the time I dialed the number until the problem was fixed.
Several files on the gps were corrupted. So they had to reinstall those files and reinstall the maps. My "Base" maps were there, but the detailed maps were completely missing. I spent probably 2 1/2 hours of the 4 hours waiting on hold. The other time was spent with 3 different support people. The last one was a genius.
Anyways, I'm thrilled it's back up and running properly. I can go to places again!
