I just traded in my 2020 Denali 2500HD for a 2024 model. I'm very disappointed that the rear door lock buttons are not there on the '24. Denali Ultimate is supposed to be the top, right?

There have been a lot of problems with the rear trailer cameras, whether using the transparent trailer view or just the trailer camera view. Mine has always had the problem of freezing, then going black after a short time (about 10 to 20 minutes). I have to turn the truck off and wait a few minutes to get it started again, but same the thing happens every time. On a previous forum conversation string (that I can't find now) several owners have experienced the same thing. One discovered there were seven iterations of the camera. I purchased the vendor supplied camera in February 2020, so I probably have one of the first iterations. I think GM released this technology before it was ready and is BETA testing on us. The only time the camera worked for a longer period of time was when I started it and immediately got stuck in a three hour backup on the freeway. It worked the whole time going no more than 10MPH. As soon as I got past the roadwork and sped up it quit again so I think speed is a factor. I had my dealership replace the camera module behind the back seat last month. They also found a water leak in the rear window and had that replaced by an automotive window vendor. The leak was right above the camera module so I was hopeful it would work now. No luck. I experienced the same symptoms of camera freezing, then going black. I did notice the initial calibration of the transparent trailer view worked much better, though. P.S. My travel trailer is 35 feet so I had to lie to the truck when inputting the length. It makes the transparent view a little distorted on the left and right edges, but that would be fine with me if it just didn't quit working every time.

I just had my windshield replaced on my 2020 2500HD Denali. The head up display appears to have moved to the right and is not quite as focused as before. Does anyone know if the HUD location and focus is adjustable?

I have similar issues. The rear trailer camera usually works at first... for about 10 minutes, then it freezes (becoming a picture), then it goes black. The really frustrating issue is the view is black when I get to my destination and need to see behind the trailer for backing. It comes back on if the truck is turned off, but it's inconvenient to do this at the destination. As far as the transparent trailer view it hasn't worked since the first trip. This isn't a big deal because the camera has such a wide angle view I can't see much behind the trailer unless it's very close to the bumper. My travel trailer is 35 feet from bumper to hitch. I was disappointed to find out you can't enter more than 32 feet. When it worked, the view was slightly distorted. Now the progress bar doesn't even start, let alone progress.
