Total Camera Failure

I drive a 2020 Sierra 3500HD Denali 4X4.  Used mainly for towing a 5th wheel.  We purchased the GM rear-view trailer camera and had the RV dealer install it.  It works fine, but this has happened twice (out of maybe 40 hitchups) . . .

 

During the process of hitching up, everything works fine.  One of the last things we do is turn the engine off, plug the rear-view trailer camera in, and then restart the engine.  Cameras all work, we're good to go.  But then after we shift into gear, ALL the cameras go dead (except for the rear-view mirror).  We turn the truck off and restart . . . doesn't help.  We call our GMC salesman who helpfully suggests that we disconnect the battery, wait 15 seconds, and then reconnect so the system can reboot.  This works and we're off.  He also intimated that a software update from GM might fix the issue.  This has only happened during hitching up, never during an unhitched start-up.

 

Today we took the truck to the GMC dealer for routine maintenance and the Service guy said he is unaware of a bulletin, notice, or rumor regarding camera failure.

 

Has this happened to you?

      Trailer Cameras Not Working
      By Bazel
      I purchased my 2020, 2500 Duramax in September. I ordered it with the all of the trailering features.
       
      I also ordered an auxiliary camera to attach my travel trailer, which I installed in November. 
       
      It worked great for the first two months.
       
      Six weeks ago it stopped working completely. 
       
      I tried every combination of plugging and unplugging, cleaning connectors, switching between the interior and exterior jack.  
       
      Finally, I removed it from the trailer and took it to a Chevy dealer.
       
      They let me plug it into one of their trucks to see if it was the camera or my truck that was the issue.
       
      The camera did not work on their truck either.
       
      Chevy sent me a replacement camera under warranty, which I received last week.
       
      After installing it, it worked great for two days, then stopped.
       
      Has anyone else had similar problems?  

       
      Thank You

      Denali grille to SLT (camera & install)
      By ZeeDunny
      Just picked up a Denali Grille w/ camera and am wondering if anyone has done the install themselves and ran into any issues hooking up the camera? I’ve only seen a few videos online of the new body style sierra grille replacement but am unsure if the camera addition will give me any issues. All help appreciated!  
       
      Will be posting before and after photos as well??

      Front camera
      By FuzzyNuggets
      I own a 2020 trail boss and it boggles my mind that GM did not offer a front facing camera on their off-road purpose TrailBoss! Not only would it be great for parking but even more important when approaching off road obstacles. Does anyone make or have installed a front facing OEM style camera that integrates with the RPO code IOS 7” screen?

      Upgraded Backup Camera?
      By Ryan Amey
      Has anyone tried or researched upgrading the factory backup camera? My camera is very blurry in my 2014 Sierra SLT and am looking to improve the quality. I’ve seen cleaning the lens on the current camera so I’ll try that but I’m not ruling out a replacement camera if there is a higher resolution option on the market. Before anyone asks, yes I cleaned the dust and dirt off.
