I have the same problem with my 2015 Silverado. I was hoping to see someone had a fix for it but unfortunately it looks as though I will have to deal with it. Dealer tried everything from software updates to replacement parts till they told me they could replace the screen. I don’t see how that could fix anything as how can a replacement radio fix the instrument cluster screen from changing from speedometer to radio. I think it’s a bug in the computer that they don’t know or care to fix.
