Hey friends, my 2018 Silverado radio has started acting strange. A couple weeks ago, I had the radio continuing to raise the volume to full blast. Whatever I tried, turning the volume knob down or the steering wheel control down, as soon as I let off the volume would start climbing again. I ended up stopping, turning off the truck, opening the door and restarting and it was fine.
Today as I switched from media to radio, the screen kept changing to a list of XM stations. I went back to media and then the scree would change to a list of songs on the flash drive.
I am at a loss of where to start. Any ideas would be appreciated.
