Trailer Camera

[Msraustin]

I just bought a 2020 GMC 2500 SLT(really good price) but it didn't come with all the fancy cameras. I would love to add the trailer camera but the truck doesn't have the 2 plugs above the 7 pin plug. I assume this isnt going to work but I wonder if I can buy the oem parts and just add it. But I bet the BCM controls it. Wish I could add all the cameras

Did you ever find any information on how to add the ports?

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.

Thank you,

 

I guess I missed something... I have a sliding rear window and the touch screen infotainment.  I'm not even sure how to check/find build sheets to determine if that means I have the IOR.

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

Bumping this as I have found some information that might be able to help those looking for this info. Once I get my truck in, I will try it out and report back:
 

Based on a few threads between 1550 and 2500 forums, the following 3 OEM parts would be needed to retrofit the vehicle to accept the OEM AUX camera(s) so long as you have the IOS Premium Infotainment System (if you have 'trailering apps', then you have it):

1. Swap out high-mount third brake light to part# 84699124 (w/ bed camera w/o Mirror camera -- ~$100)
2. Swap Trailer harness receptacle with part# 13530416 or 13526856 (~$75 - $95)
3. Add OEM Video Control Module 'VPM' 

Open question: Does the IOS infotainment require an update or will it recognize the VPM & additional camera(s) once plugged in? Are pigtails for the VPM already prewired into the body harness? 

My build for reference: 2022 2500HD SLE w/ Premium GMC Infotainment System and Trailering Apps. Unfortunately the dealer did not advise me to add the $250 bed camera option to ensure invisible trailer works.
