Explorer 510 Locks Up
After about 40 minutes being just fine, my new eXplorist 510 locks up and I have to remove one of the batteries in order to get it back on. All I have done since I bought it was update the newest maps and firmware and I geocache with it constantly and it is getting real annoying have to reset it all the time. Is there a setting that is causing this. I really like the unit, but am really bummed.
