2020 Sierra 2500HD back up camera not working

[Jonathant34]

Has anyone ever seen the attached icon display on their radio when I put the truck in reverse?  The same icon comes up when I try to turn on the camera as well. 

 

Thank you in advance.

I just got that same Icon Error today, and how my Bed View camera stopped working. Strangely, my bed lamp turns on instead when I press on the bed camera. Frustrating...I am going to call the dealer tomorrow

My truck did this the day I brought it home.  Dealer ended up replacing the computer module (behind the rear seat on my crew cab) but I suspect it was possibly not fully connected during assembly because during the diagnosis they disconnected and reinstalled and it worked for the next several months and at least 5000 miles while we were waiting for the replacement part.

Did you ever find out what the problem was ? My husband bought a 2022 gmc at4 2500 Duramax and it started doing this at approx 1778 miles odo. GMC service dept doesn’t know what is wrong. They did software update and supposedly replaced the screen but still doing Same.
