We bought the Rear Trailer Camera (84876819) for our 2020 Chevrolet Silverado. We want to make sure that the camera works prior to mounting it on the trailer. We connected the trailer to the truck, plugged in the camera, selected the Rear Trailer View on the display, but the view is black, there is no picture. We didn't calibrate it like it says in the instructions since it wasn't mounted. Do we need to do this or is there possibly something wrong with the camera or the connection to the truck?

You connected trailer -- did this include plugging in the trailer 7 way plug? (this is what activates the camera connections)

 

Did you try the instructions on sheet 7 for how to 'test the view of the camera'?

Yes, we did plug in the 7way plug for the trailer that is already in the trailer profile. On the instruction sheet on page 7, we did not calibrate the camera because the camera was not attached to the trailer yet. We were hoping to be able to ensure that the camera and the plug worked prior to installation.  When we selected the rear view camera, the screen went black although inside the eye of the camera you could see the eye rotating. 

 

Maybe we need to do go ahead and mount it and calibrate it. We were just hoping to verify that it works first.

The way I read it, the ' Test the view of the Camera' instructions it is possible to do what you are wanting, and test the camera view without mounting or calibrating.

 

 

I've only had mine a couple of days and haven't tried it yet to verify that those instructions work. 

 I intend to do the same thing as you, and test before going to the work of installing harness and camera. 

 

Did you also try it on the 'inside trailer' connection?

I guess I'm assuming that the same camera type can be installed for either job.

Did you get it working? 

 

 

For others that may be interested.

 

You can easily 'test' the camera without installing.  

 

I created a trailer profile.  Just entered a name and basic info. You may be able to use the 'guest' trailer entry -- but I didn't try it.

 

Connected trailer plug to truck. 

I did NOT connect the truck to the trailer.

The alignment key on the truck plug is at the top -- where it's hard to see -- it is possible to push the plug part way in with the notch/key not correctly aligned.  Naturally it goes in further, and much easier, with it correctly aligned. Incorrectly pushed in lights won't work and 'check trailer wiring' message is likely to pop up.

 

Selected the named trailer from the list -- or create a name if that wasn't already done.

Verified that the trailer lights are working.  Used the trailer lighting test feature that cycles through the blinker/4way etc to eliminate a lot of walking and to not need a helper.  (they should have added light test feature years ago...)

Camera will NOT function unless the trailer plug is installed so the trailer lights are working.  Seems the software doesn't turn on the camera module unless trailer lights working.

 

Unwrap enough cord from the camera so that it can be plugged in without fear of the camera lens getting damaged.   

Plug in camera.  Use the 'rear of trailer' connection

 

In the trailer app press the cameras button.

Will be able to use the choices button to select the camera only, or the camera in combo with the mirror camera. 

On mine this button was on the bottom LHS of the screen.

 Repeated pushes of the button will scroll thru the mirror / rear camera combos.

I see this post is quite old, but it may help me.

 

I have the trailer camera installed on my RV. It worked great on my 2023 GMC Denali. I had transparent trailer, backup lines with guidence, blind spot, everything worked as advertised. 

 

I purchased a new truck, 2025 GMC Denali 2500HD. I synced my GMC account and my Trailer Profile with the GMC app. Selected my trailer profile in the truck, plugged in the 7 pin and my Trailer Camera, and selected the camera and I have a Black Screen. When I check the profile, it seems like the camera is connected (It’s selectable) but only a black screen. I rechecked all the different trailering options and making sure they all copied over from the other truck and trailer profile, I’m still getting a black picture, and the hourglass in the top left corner. 

 

I tried switching the camera to the interior trailer cam jack, and it recognizes it’s been plugged in, but it has a black picture.

 

Hoping someone can help me troubleshoot this, I really use it to back into RV spots and into my storage.

I'm gonna assume both your trucks were 2500's -- so one with the refreshed interior and electrical system and one with the 'old' system.

(for 1500's, the '23's had the new electrical system)

 

Did you get a new camera for the 2025, or are you using the one from the '23?

 

One 1500's, the pre-refresh cameras will not work on the new electrical system, so HD's likely have the same issue.

 

Good news is that the new cameras are reported to be clearer.

You may need software update from dealership. TSB 23-NA-053 Radio Software Version U168 Update.

I had blank screen on my 2020 Silverado 1500 until this was installed. Check out this post with link to TSB:

Thanks REDWNGR,

 

Yes, I found the problem with your help. My 2023 was a GMC Denali 1500 (New Interior), my new truck is the 2025 2500 HD Denali, I see that the part numbers changed for the auxiliary camera and they are not compatible. I also found that I can simply swap out the camera, and not have to re run the entire wire harness, it’s just a matter of purchasing the $95 camera and opening up the existing with a security torx. I’ll update after I do the camera swap.

I’ve got the camera swapped out, now I’m working on getting it to calibrate. I placed the camera at the same angle I had the last one, I can just see the top of my bumper, but it won’t calibrate. I went back and looked at the setup guide and it appears I measured the 35 deg from vertical, not 35 deg from horizontal. I didn’t have any issue with the old setup, but maybe fixing this will help. Resize_20250120_135808_8131.thumb.jpg.0b31de2c74da922e77a89c7cb6670efe.jpgResize_20250120_135809_9461.thumb.jpg.f16b93d6ea24231bcaef9789a1147bf8.jpgPXL_20250127_174622572.MP2_Original.thumb.jpeg.c39bf31916c548c6d0b91b1623b629c2.jpeg

Can't help you with the calibration, my original one took forever where i live to get calibrated this one i didn't even bother as i use manually for seeing behind me traveling and backing up only not worried about the transparent view i keep full screen on that camera only.  it stays on until using directional.  My camera on enclosed car trailer i mounted to the top/roof and don't see the trailer when ramp up

Thanks again for the help!!

 

I got it all worked out. Someone mentioned the 118 inch height bug, I reset it to 117 inch and changed the angle of my camera to 35 Deg from horizontal (Not from the wall which I accidentally did) and it calibrated in 200 yards!

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
