I don't have alot of info to add.  It sounds like either a connection issue or some type of software bug.  I have had to setup about 50 trailers for demos but once I learned some of the setup issues, I haven't worked through any type of issues like you have mentioned.  Wish I had more to add.

HEY MTU-

I ask because you have been very helpful with this stuff. Any idea why my "invisible" camera mode needs to be re-calibrated every time I hook up, or have a gas station break, or stop for food? It's pain to drive the length of a football field while going 5 miles an hour to calibrate this thing every time.

Shotgun,   I agree, the key with these cameras is the awesome ability to see behind your trailer. It is really a cool option to have that functionality integrated in. The transparent thing i

I usually backup to trailer and get aligned to trailer hookup, shut truck off, hook up trailer and chains, then plug in electrical, and finally camera.  These cameras don't like a hot hookup where the

You can put them on 5th wheels, you just won't have the transparent trailer view. However, the view with the mirror cameras and rear vision camera is pretty dang good.

I don't.  I assume you are selecting your saved trailer profile when hooking up.  You shouldn't have to re-calibrate after you have done it once.  Let me see if anyone has any ideas to try.

Ok.  I asked around and here are a few things to try and make sure of.

 

1.  I assume you are selecting your trailer profile at startup and not changing any the of the dimensions.  If you change any of the dimensions it will cause you to re-calibrate.   

2.  Just confirming that you are getting a yellow status bar and showing calibration being done on the Transparent view after each startup?    You have to be going 10 mph for the transparent to work after a key up.    

3.  If it is really calibrating after each key cycle, I was told after the calibration is complete and transparent is visible to shut the vehicle off and let it the truck go asleep.   Basically, shut the truck off and open/close driver's door and wait until the Onstar green light goes out.    From your post, this should have happened at your gas station and food breaks.    When the module goes to sleep, it should write the calibration values in memory.  

4.  Its probably worth trying creating a new trailer profile with the same dimensions and see if for some reason that profile is corrupted.    

5.  Take some pictures in transparent view with it calibrating and once the calibration is complete.    If it is calibrating, in the transparent view you should see the view with the two mirror cameras with the trailer camera in the middle with a yellow status bar at the bottom of the screen.  

6.   Take to Dealer and see if there are any codes for loss of communication between the CSM (Radio Display module) and VPM (Camera module).

I have not tried a different truck yet. It really does seem like a power issue with the way it "knows" a camera is there, but shows no picture. Then, when unplugging and then plugging into the other port, it is great. I had issues from the start with the hookup process, powering down, etc, but this issue has remained. It will work great, then go out, then work again. The biggest problem is when it decides NOT to work when I need it the most, like backing it a tight spot or checking spacing. I may just try it on the interior camera port next trip and see how it does.

Hey Shotgun...

 

I have a few more data points; have you learned anything new?  

 

I've been having radio problems (particularly with XM) so I took my truck in for service.  While there, I told my service advisor about the problems with the trailer camera.  Since they couldn't replicate either issue, they informed me that there were no problems.  When it arrived, I filled in the customer satisfaction survey with my true feelings.  A few weeks later, I got a phone call from GM Corporate wanting to know more about my issues.  They set up a service appointment with a different GMC dealer, who listened to my issues and did a fair amount of diagnostics.  The XM radio problems are not unique to me, but it appears to be a problem with SiriusXM and not GM.  We are awaiting word on resolution.  As for my camera problems, my service advisor told me that the camera system "threw a lot of codes" so they know something is wrong.  They are awaiting some parts to fix my issue, which are apparently on backorder at the moment.  He's been a bit cagey with details, but I'll post here when I learn any specifics.

 

After nearly a month, I got my truck back (radio still not working) this week.  Today, I picked up my Airstream.  Initially, the backup camera / invisible trailer view worked per design.   After a few miles, it froze then eventually went black--just like before.  I reset the trailer plug, and the camera worked again.  But this time, I never put it into "invisible trailer" view; instead, I left the rear view camera on for several miles until I reached my destination.  The camera worked the entire time!  So here's my theory:  The camera works fine, but the invisible trailer processor is causing the apparent problems.

 

Shotgun, I have a request for you:  The next time you're pulling your trailer, can you NOT use invisible trailer view and just leave it in rear view only?  Let's see how that works for someone other than me.  We'll have the trailer back out in a week and a half, at which time I'll try further diagnoses along these lines.  Hopefully you can help shed some light on this.  My XM problems and trailer camera problems are still highly correlated with each other, so I still think they are somehow related....

 

Thanks,

   Jayson

Have you tried to refresh the radio to resolve XM radio? Mine has been acting weird and stopped working Sunday and refreshing my radio ID fixed it. It took a few mins but was fixed in a few miles after submitting.

 

Yes, I've tried this about 20 times, and so has the service department at the dealer.  This has had no impact.

 

I'm having some really specific, strange issues with the radio.  My service advisor reports that GM is aware that some trucks are having these same issues, but they have not yet identified a fix.  Most recently, GM thinks the problems are on SiriusXM's end.

 

I'm suspicious of their assessment, because my radio problems are exacerbated by plugging in trailer the 7-way plug.

I figured they had tried all kinds of stuff, but wanted to throw it out there.

Hope you get a resolution soon.

Jay - I don't use invisible trailer as my camera placement is too high and trailer is too long for it to calibrate correctly. The only views I have is rear-view only and rear-view with side mirror cameras. I'll see if it's any better next trip or if it works better using the interior camera port on the bumper. 

 

Interesting that they found codes on the system. Next time mine goes for service, I'll mention it to them and have them check it out. Hope they narrow yours down and get it squared away. Maybe the processor is the issue, like you stated, and GM will update trucks that have the issue.

Ok....then next time, just use the pure rear view.  Mine has "locked up" in the combination rear/side view; when I was only using rear view, it worked the entire trip.

Interesting topics.

We have had the XM issues from time to time where it doesn't seem to connect. If I change the channel it starts playing an I can go back to the normal channel. Last time I got in the truck it worked ok.

 

On camera issues ours is a travel trailer so camera is above the rear window and I figure i is to high to calibrate as we have tried it a couple of times.

 

Took the trailer to have serviced about 60 miles away. Camera did fine as it always had. When we picked up trailer the camera would work. After reading the suggestions on here I hooked the truck up yesterday after letting the buss go to sleep. It worked fine.

Funny as every other time I hooked and it worked. the engine was running. Don't know if I hooked up the 7 pin connector first or the camera connection. I do know once or twice I had to unplug the camera and plug it back in while my wife watched to see the camera start working,

 

Will be trying it again in a few days so will be interesting to see if it works.

 

Wish the trailer pressures could be displayed on the main dash display.

 

Thanks for all the info...

I tried it using rear view only, still froze intermittently and then went blank. I then unplugged it and plugged it into the inside trailer port and it did the same thing. Here’s the kicker, it seems to freeze up more when moving and it’s trying to show the video. Your dealer may be on to something about the processors. Maybe they can’t handle the active video, but still or slow, they do okay sometimes ?

That's not the result I was hoping to hear.  Thanks for the update.

 

We're camping again next weekend, so I'll try a few more diagnostics and report back if I learn anything interesting.

Well it would be nice if GM would offer a camera and the options necessary for us guys with the big 38+ ft 5 er's.  I would love to put the camera on the back and have everything incorporated on one screen.  Currently the camera they offer does not have a long enough cable.  Plus why wouldn't they put the stinkin video ports in the bed of the truck also.  That right there tells me they never thought about using a camera on a gooseneck or 5th wheel.   Doesn't make sense to me.  I keep looking for the style plug they are using  to come up with something on my own. Does anyone have an idea?  Problem is right now these trucks are so new and  if we want these options we have to come up with solutions ourselves.  I will give it to GM they put some thought into it but it seems they forgot about us guys with the big trailers when it comes to the optional cameras.

Below is a link that tells you what to buy from where to relocate the bumper plug into the bed. I have done it and it was very easy but my camera is still on backorder so I have not been able to try it out.

      By Chuck FB · Posted

      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.
