Every morning I would start up my car and drive down the road, for the first 15 minutes if I was listening to the radio I could not switch over to a CD or if I was listening to a CD I could not switch over to the radio. It was only after my car had been sitting for awhile. However I also had an issue w/ the clock also. I would try to set the time after time changed and it would not let me scroll through to change the minutes or hours. They still are unable to figure out the issue with the clock and the radio/cd.
