Just purchased a 2020 Sierra 1500 AT4. It only has 500 miles on it. Got in the truck today, and the audio had completely stopped working. No radio (FM, AM, or XM), nothing from my phone via bluetooth or USB, no audio warnings for no seatbelt, etc., no voice recognition feedback....you get the picture. Anyone else having this problem? I see where this has been an issue for some of you, but no recent posts. Any updates?
Taking it to the dealership today, will post if I hear anything about this problem.
