Mike Smith

I have the same issue 2015 2500 HD LT the GPS drifts cant rely on it at all happened all of a sudden, also the MPH on the screen behind the steering wheel keeps reverting to xm radio. Dealers just want to sell a new radio. I dont believe it will fix it due to its not just a radio it has several separate devices all sharing the same screen. I guess only recourse is to live with it.
