Well. I have the package and the camera on my 2020 NHT SLT.  I have a buddy with a 2020 Denali 3/4-ton that has the connection as well - but since his has the 360* cameras, his didn’t come with the separate cam.

 

I will go see him tomorrow and take my cam and we will just try it out. 

Ok. No real news. Took cam - neither truck recognized it.  It looks like it has to be set up on top of the trailer or camper. There are instructions to set it up in the center of the camper/trailer and to ensure the lens is angled at 35*.  Makes sense since it’s supposed to “see through” the trailer.  
 

Tried connecting his trailer thinking it may need to see a trailer there with the light hookup and even created a profile for the trailer. Nope. Tried both cam inputs. Left and right. Nope. That I thought for sure would work because one was supposed to be inside the trailer.  
 

It was sleeting and freezing rain on us for the appx 45 minutes we were messing with it. I’ll just wait and install it on the camper and do it right. Once it’s hooked up and working - we will try his truck out on it. 
 

Sorry!

I work at a GM store and I am looking at getting a new body Silverado and ran across this issue myself. I want the "HD Surround Vision" camera package, but I am finding out that it isn't compatible wi

@Gypsy1962 did you get any good results after hooking everything up?  I'm in the same boat with the technology package and no aux camera option.

As soon as you plug in the camera it should show up on your screen.  It may not show up in the "see-thru" mode but you will see something.  So I would check that out first.  I hate to see you go to all of the work installing it on the trailer and it still does not work.  

 

When I did this (I have a 19)  I found that you had to really secure the camera cable to the bumper plug.  When I initially did it I didn't have a picture.  I had to go to the back side of the bumper and push both cables together.

Ok - I didn’t do all that - but the truck did recognize something was hooked up. I tried to view and it only showed the view from the tailgate cam, not both. I still had the aux coiled up and it was resting on the tongue of the flatbed trailer. 
 

Had it not been nasty weather - I would have been more determined to get it going.  Next “decent” day I’ll give it another shot. 
 

Thx for reply about your experience. Owners manual is less than helpful at this point.

Ok. It works. On mine - haven’t had him come over and hook up to it yet.  I did install of cam on camper - followed instructions - and another person’s recommendation on connections. 
 

As I didn’t want to remove existing camera mount (mount only - no cam) which was wider and would have shown holes or had me patch and match - I mounted cam base above existing. 
 

Once it was centered and aligned - I temporarily ran cable to back of truck. 
 

Had truck off. Completely “dead”.  No ticking, clicking or noises. Connected camper wiring. Connected camera to right side plug above camper plug. 
 

Started truck - set up camper profile to include tire pressure settings (had them already installed from my 19).  Checked rear of trailer camera view from home screen and it worked.  Still does not work from in the trailering app on truck. Can see the icon for both the cam on rear of trailer or one for inside trailer (which I don’t have). Push one for rear of trailer and is tells me to connect it.

 

Oh well. I can see it fine from selecting cameras from the home screen. 
 

Maybe tomorrow I’ll have my buddy come over with his 2020 3/4 ton Denali with the technology package and give it a try. 
 

(I have not yet moved camper to test how long you’re able to view while I’m going down highway).

Mine is similar to yours, but dealer did not add PTT to the build sheet. I got an older set of 4 from ebay for $25. As long as they are 433mhz, they should work.

 

 

Optional (and not available on base sierra)

PTT         Trailer Tire Pressure Monitor Sensors, includes set of 4 sensors. Sensor functionality requires (U1D) In-vehicle Trailering App to be ordered with the vehicle and installed by the factory. Sensors will be shipped loose with the truck and will need to be installed on trailer by customer. System is capable of monitoring up to 6 wheels. Additional or replacement sensors are available through GM Accessories
1 - Requires (ZL6) ProGrade Trailering System or (PDQ) Preferred Package.




Any update on this? Have u connected them to the truck and do they show both heat and temperature also?

Also interesting... I pulled out one morning with a side of my trailer that had been in the sun... I got a warning that one of the tires was much hotter than the other three a few miles down the road. Seems like a super useful thing to have.

Can anyone verify if this is the same connector from the trailer camera that plugs into the back of the truck?  Thanks!

My camera wires were connected to that blue plug before they were connected behind the bumper.  I had only one connected and connected the other myself, now I just need a camera. There are two of those blue plugs connected to nothing behind my bumper.  what is your plug connected to?

This is the harness that is in the headliner that runs from the rear view mirror to the camera in the third brake light. I bought this harness to see what connectors it had on it. I have installed a cap on the truck, so now that camera is blocked. I was going to try to make an ‘extension cord’ to extend that camera and install it on the back of the cap. If the camera that mounts on the back of the trailer has the same plug, I could buy that which has 30 feet of wire, mount that on the back of the cap, plug it into the harness in the headliner, and have that camera on all the time in the rear view mirror, like it is now. I just don’t want to spend $400 dollars or whatever on a guess that the connector is correct.

The rear camera wires plug into that blue plug on the open end pictured.  The opposite end with the white cap was blank with no wire.  just used to hold the wires up out of the way.

I'm wanting to install a camper top on my 2020 HC but hate to give up the rearview mirror camera like you mention. Have you tried removing the 3rd brake light assembly to see if the camera can be taken out and possibly moved? Please keep posting anything you come across and I'll do the same.

I will definitely post what I find. Looking at the breakdown at the dealership, it looks like the camera has two screws that hold it to the 3rd brake light. It also appears that you can order the 3rd brake light with a camera hole, but doesn’t include the camera. Or you can get a light with the camera included, but you can not purchase the camera by itself. 
 

I ordered the harness that connects from the camera in the brake light to the rear view mirror to see what the connectors looked like. (The picture above) I was hoping that it would be long enough to use as an extension and remove the camera from the brake light (or order a new one) and mount it on the cap. But the harness is only about 24” long. My new thought after I got the harness today would be to install the trailer camera, which already has a mount, and Is designed to be outside in the elements, and has a cable that is plenty long. I might try to order one tomorrow.

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
