I have the double cab and the 8 inch screen. My am works and fm too. However, my HD is the problem. My Kenwood in my last truck worked great. So this HD issue is A GM problem. We did not want to pay so much for this truck and hear we are working on it. I took my dealer. He says it is up to specs. So I said to the service have the tech take a ride with me. He says he can't let him go. Is that service when you pay $40,000 plus
