Adding hard button for camera on 2021

[peterlawl84]

I have a 2021 Yukon xl and was wondering if anyone has tried swapping out the switches to a 2022 for the hard button for the camera. I know it’s a long shot, but any chance it’s doable?

asked a dealer and they had no idea.

Man, this forum doesn't get as much help as the truck side of things.

Anyways, update on my question.  IT IS PLUG AND PLAY for my 2021 Yukon XL Denali (build date May 2021).

 

Several people were saying it was not possible and just to trade up to a 2022 model, but I didn't want to lose any features I currently have. This was by far the best $70 I have spent on this vehicle.

 

There are 25 part numbers for the switch with camera, so you will need to figure out which is correct for your vehicle based on RPO's. Parts guy at the second dealership I went to (first was not interested in helping me) was willing to print out the list for me to figure out which it was as he could not find it based on a VIN I gave (I have attached the part numbers pages so hopefully others can find their's easier). 

Mine was an ultimate:

UHX: Lane departure

JHD: Hill Descent

UD5: parking sensor

KL9: Auto start/stop

UV2: 360 camera.

Z88: GMC

 

Other RPO's listed:

NSS: no start / stop

X88: Chevy

 

You can find your RPO code on the driver's side door jamb and scan it with your phone camera to read it.

 

Once you get the part, it literally took less than 10 minutes. 

1. Popped off the 2 panels: Do the bottom left of the kick panel first, then do the side piece. 
2. remove 7 mm screw that holds the trim piece with the switch.
3. pull straight out on the trim piece with the switch (4 retainer clips, see picture).
4. remove clip but first using small flat head to slide red locking piece out (to the right in the picture) and then flip green piece down and it will release the harness.
5. Remove switch from trim piece with small flathead to release clip at each corner.
6. Install new switch and then put everything back!

All buttons working and no programming needed!

Very informative posts. I have a 2021 high country suburban with the same switch setup as you. Ordered part # 84786497, I will report back with another data point after install. I also plan on installing an auto stop eliminator at the same time. 
 

FYI, for anyone with a non Denali Yukon or Tahoe/Suburban the switch panel disassembly/assembly is covered in a video on the auto stop eliminator web site.

Installed my switch panel today, everything works as advertised. It’s nice not having to navigate the touch screen to get the 360 cameras up. Thanks peterlawl84 for sharing the information to make the swap possible.

Thank you for all your help on this! We have an 2wd Duramax Yukon SLT that does not have Hill Descent Control. I ended up ordering the part number 84786496, and I also paired it with the auto stop eliminator and everything works great.

My 2021 Suburban controls do not have the hill descent button.

It looks like b0hr found the right part to substitute to get the camera function.

 

But, if I add the button assembly that peterlawl84 used, will I also get a working descent button?

Is that plug and play also?

b0hr, what is the auto stop eliminator and where do you get it?

I can guess what it does but what does it look like and how is it installed?

I found the autostop eliminator:

It’s what you expect. It remembers your preference of keeping auto-stop on or off between engine starts. Install video is on the page as well.

You will not gain descent control. thats a separate module.  This has been confirmed by others that tried to use the same button I did on their vehicle without it.

Another successful installation. 

As noted by b0hr above I used part number 84786496 for my 2021 4WD Suburban LT.

I also installed the TRL Autostop Eliminator at the same time.

Everything works great!

OMG this has been driving me crazy ('21 Yukon Denali). Stumbled upon this thread and just ordered the upgraded part (84786497). Can't wait to have a hard cam button - thank you, all!
