Radio control screen problems

[Jim Burriss]

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.

remove the glove box to get access to the hmi and make sure all the plugs are tight

Ok thank you. The dealership just had to replace the vacuum pump for the brakes. They might have hit it.

Any luck here? Having the same issue with mine doing the MPH to Radio switch. The radio also just started randomly clicking things as well. Going to try to make sure the HMI is all tight but may include a battery unplug for 10min and see if that helps.
