I have a 2015 Silverado I was driving down the road and my display with the MPH showing went from there to what was playing on my radio. I went back to the MPH and it went straight back to the radio station again. Then when I went to use the push button on the radio screen to change the channel it wouldn't change the station. I could do it manually with the knob and could change the volume with the knob. I really don't want to take it to the dealership to have them charge me an arm and a leg for something simple that I could do by myself. Does anybody have any suggestions.
