Report po Sean, I have the exact same truck as you...2015 Sierra SLT and I'm having the exact issue you had with your radio. I have researched this for several months now. I was told it was a faulty touch screen, a bad circuit board, HMI unit going bad, etc, etc. I hated to spend big bucks chasing this issue. I recently purchased a complete dash cluster from a totaled 2016 Denali for $170. Installed it and it worked great...for 2-3 hours, then the same issue began again. So it took $170 to determine it's not the touch screen and not the circuit board it plugs into. Now I'm wondering if its the HMI unit under the glove box, but those are $700! I hate bring it to the dealer 'cause I know I'd get shafted. I got a quote for an aftermarket system and that's $800+! I believe I'll do the Dealer because if it doesn't work then, they have to figure it out. Sent from my iPhone using Tapatalk
