My 2015 Silverado Infotainment Screen was switching itself from the Radio Screen to the XM Station List Screen and also the Info/Speed Screen on the Instrument cluster would switch to the Audio/Radio Channel Screen & the Touch Screen was unresponsive. I did the "Touch Screen Recalibrate" and it fixed it for 3 days. Then it got worse. So, in the settings menu I Did the "Return Radio to Factory Settings." So far it's working okay now for a whole week. Maybe it had a virus? You will have to reset your Saved Radio Channel Selections. I only re-saved 8 so far and it's working okay now.
