My battery was getting bad in my truck for a few days. Had to jump my truck a few times. The one day I noticed my music/nag center would not work. None of the buttons would work and the screen was black, however the music would still playing and i could turn the volume up. The next day I had to jump my truck again and then my music completely stopped working. Any idea why? I called ford and they said I would probably need to take my truck to a dealership to have it reprogrammed. Any thoughts on this?
