DunRollinOut

Almost exactly the same issue. I live in South Texas, Out of the blue started to roll through all the screens, highlighting various stations with a white box. It would pull some menus into to others, scroll to the apps screen, roll to the warning screens, the one that really fried my bacon was when it started changing stations in mid song, conversation. Oh yeah, wouldnt start until about 10 to 15 minutes into the trip, so when took it to dealer, they looked at me like a space alien....................................Silverado HD 20017 HD, bought new, but drove the crap out it and now have 40,000 + miles on it.......So far the Dealership has said that are familar w/problem, and replaced screen? No sooner then got it back. 10 to 15 into drive........TaDah........Started again....I am very frustrated..........Im thinking replace the computing unit? Have already spent 800....Is there a better way.. Warranty expired....It is looking bleak. One more try then Im going off the grid...
