So as the title states. I have 2010 Yukon XL Denali and as I am driving down the road it randomly changes the station and DVD. It is not induced by bumps. It is just random. I have done some research and a few other makes and models have stated that it could be the steering wheel controls, but that does not explain the DVD. Also it does not give and actual fix for the problem. If anyone could help it would be greatly appreciated.
