I have a 2016 GMC Sierra with the touchscreen radio (no steering wheel controls). So far, radio display frequently changes to stored station and favorite station screens. Have had one episode of random station changing. Has not occurred again. Occasionally, radio display unit does not function (entire unit inop: blank screen, button pressing does nothing, rear camera inoperative). After being parked for a day or more, normal operation resumes except random screen display changes. I have not contacted the dealer. Am guessing GM does not want to own this one.
