Just use your camera on your phone and scan the QR code inside your door. It will list all the build codes for your truck

It is going to be a radio issue. If you have anything but and IOR radio you are in luck. I am experiencing the same thing trying to get side view cameras. Basically you have a sliding rear window or you don't. From my digging so far all I find is a different wire harness with an additional 2 pins for the upgraded infotainment systems. I am exploring my options for different camera views using a full display rear view mirror. Unfortunately the center stack is not looking promising. I am still waiting to hear back from the dealer. The dealer isn't telling me it can't be done. It just requires lots of the dash to be pulled out. It looks like GM may not be willing to sell the harnesses or the radio equipment. Anyone can get the radio equipment from Infotainment. The problem is the lack of wiring harness to connect it all. I am sick of folks tell me to go buy a new truck if I want cameras..... Maybe one day when they want a new outlet in their home they will be told to go buy a new home that already has the outlet they are looking for. BTW to all those folks out there try and go buy a new truck that doesn't exist.

I am unsure on the 2021. The pervious gen i had the same issue and just tuned the bass all the way up. I thought it would be terrible but it almost passes. BTW if it's got no highs and no lows it must be b0se....

The seats are terrible. I like my 19 much more than my 20. The more I compare them side by side the more I see how they missed the mark in the 2020. I saw that someone posted that there is a tilt telescoping wheel in the 2020. This simply is not the case. The 2020 has a tilt telescoping column. The wheel itself has almost not range of motion the column just moves up and down. The wheel doesn't have any real tilt to it. It is just another one of those things that makes the new truck more uncomfortable then the previous generation.

Is no one else a little frosty that a truck with a $70k price point CAN NOT have cameras added to it that work with the center stack? It blows my mind that the only path to upgrade is to buy another truck. We are just talking about wire harnesses that can be installed and control modules that can be programmed. These are sold as heavy duty towing rigs but we can not add basic safety to them. All I want is side view cameras. The IOR does not support this is just a DUMB radio with a touch screen, but they spent the money to sell you onstar with it. You can't even add it after market because GM wanted to save wire harness.
