Cameras Not Working on 2020 2500 AT4

[nuthin_fun]

2020 Sierra 2500 AT4.  When going to the camera app, or switching to reverse, a black screen with a crossed out camera and a red triangle with an exclamation point inside displays.  The camera that displays on the rearview mirror works.  I've searched for blown fuses, but can't find any.  I've pulled the infotainment fuses and replaced to atempt to reset, and nothing.  I even pulled the disconnected the battery as a reset.  After I pulled the battery and reconnected, I started the truck and switched to reverse.  The camera displayed for a fraction of a second, then went back to the the black screen with symbols.  This is the only love I've seen out of it since they stopped working on Friday.

 

Any ideas?  Thanks!

Yeah, take it to the dealer and let them deal with it. I read in one of these threads that theres an update to the infotainment system that fixes a few problems.

check tailgate wiring  if you remove gate those mirrors you speak of dont work 

you can get a harness to plug in with a camera and mount it under truck to 

make camera system work again but gm needs a better fix considering the cost

of camera system  people with truck campers remove gate to install camper

and find this out the hard way  love the truck but did not expect this problem
