I have a 2011 regal. In the last week I've noticed that when I started the car the hour on the clock would change. The date and minute was fine. Then this week the navigation reset itself every time I started the car. Meaning that it was on due north, when I had it on 3D. Then yesterday all my addresses were erased and now when an address is stored it is not there when car is started. Taking car tomorrow to dealership. Anyone have a problem like this?
