I currently have a case open with GM about this issue, and i also made a claim with BBB, and i sent off an email to
[email protected], i am really very unhappy about this issue with no usb playback, and I'm going to go scorched earth until they hear me. I really dont care about miracast or rear maps view, but no USB playback is a serious issue.
I explained everything to the dealership and they definately agree with me that this is not a premium experience anymore, and the screens are just basic functionality now, they shouldn't even sell the option on their trucks for 2022, its going to cause a ton of grief for them, they had no idea how bad the system became.
