I tried to do a system software update yesterday and ran into trouble. Everything was going fine until the end of the system update. At that point, I lost battery power and the update was corrupted. When I start the car now, the 10" screen has garbage on it at first, then says it is preparing to update. That notice stays onscreen for a short time, disappears, then reappears over and over. Nothing further happens. Is there a way to force the update to reinstall or am I stuck taking it back to the dealer?
