Local dealer just ordered a replacement radio for my new C7! Every 3 minutes the system shuts down and reboots. Steering wheel controls completely quit working. Dealer called corvette hotline and Chevy told the dealer to not work on the car. Chevy said they would send new radio out right away. Has anyone experienced this?? Has not over shadowed my infatuation with my new car... Just let's me hear those amazing exhaust notes even better!!
