Avalon, Preset radio stations "self erased"
I have a 2003 Avalon XLS. Last week I started the car to leave work and all preset radio stations had "erased themselves". In dash clock did not reset and I noticed no other changes that would indicate a problem with the battery. Car seems to start right up and lights don't dim, so I don't think its the alternator. Any clues to what might be causing this?
