Curious if anyone has experienced this issue, and how it was resolved at the dealer. I am out of warranty by miles, so trying to get an idea of what the dealer is going to charge me and what I am going to fight since I feel like this is GM issue pushing an update I didn't ask for. I still need to visit the dealer for the software update that was issued last year, maybe this is part of the update?
I've tried the radio reset- nothing, I unplugged the battery for a couple of hours - still pops up with the same message. No stereo, no chimes, the only thing that works on the screen is the backup camera.
Did some searches on google and most of what popped up is from Reddit, I'll take their feedback with a grain of salt. If there's a thread on here, please link it and I'll catch up on the
topic.
