We own a 2017 Silverado and have Sirius Radio Stations. As the truck runs down the road, with any bumps it changes channels and the display goes completely haywire. Then back to normal. then for no apparent reason back to crazy. I was about to bring it in to the dealership with the extended warranty but with the previous comments, I'm not sure what good it will do. When you pay over 50K for an item, one would think that it would work.
