Hi all, just wanted to report that on our 2024 Suburban Z71 -- after about 600 miles we had the same problem
- 360 degree button or camera button on screen had no effect when pressed
- Putting vehicle in reverse showed the error shown in the original post
Took it to the dealer. Dealer replaced Module 87816606 - Video processing module which looks to be a >$600 OE part and of course my guess is this part needs to be reprogrammed by dealer to accept the VIN of the vehicle. (Just a wild guess someone with more knowledge can confirm).
That has corrected the issue.
Scared about the future we are heading to with all the computer modules in these newer trucks
