I have 2 different enclosed trailers with GM Trailer cams mounted to the back. I have the camera mounted above the ramp door so I have not worried about the "transparent" trailer thing. I just use the rear camera view. At times, both have worked well, but they are very finicky and sometimes display no video. Now, my snowmobile trailer refuses to display a picture. I have tried shutting the truck off, rebooting, all kinds of things I have seen suggested here to try, nothing works consistently. (Although  I am not sure if I have tried reconnecting after the truck has "gone to sleep". Wondering if anyone has found any ideas that work consistently.

 

Another issue I have is the crazy amount of force needed to disconnect the camera from the truck. When disconnecting the camera plug, it feels like I am going to pull the entire 7 pin/camera bumper port right off the truck. I have tried some dielectric grease, some other lubes, most anything to try to lessen the amount of force needed to get the camera plug out of the truck's trailer connector.  No real success, it is still very difficult. The round 7 way is fine, however the camera plug on the truck is crazy hard to disconnect from.

 

I see a number of owners here on the forums talking about their dealers replacing the 7-way.... are there known defective units out there? a recall? Even a simple non-camera connection like a single jet ski trailer sometimes require me to wiggle the 7-way plug to get all the lights to work. Maybe a new 7-way/camera plug receptacle would cure all my issues.

I don't have the issues you are having, but I did put a little dielectric grease on the seal that prevents moisture from getting into the connection.  It does make connecting and disconnecting the cable easier.

I have the camera on my camper. I’ve never had the issues you are having and it seems like you have tried a lot. If I remember correctly, there are blue o-rings on the camera connector. You might try removing them and seeing if it connects and disconnects easier. If it does, you have found your friction source. Maybe order new o-rings from GMC and lube them up and install them and see if it helps. Hope this helps some.

Yea, I need to do something... the force needed to disconnect is very close to literally ripping the trailer plug/camera connector port right out of the truck.

 

Regarding the camera connection, it works maybe 30% of the time. I connect the camera... truck off and "sleeping" sometimes I have camera view, most of the times I don't. Cannot believe GM cannot get this right. 

 

Has anyone had these issues? Any real solution. I have tried hot connection, cold (truck off) connection, wait for the truck to go to sleep connection... nothing consistently works.

I also have had the issues and feel its related to not getting the camera connection in there tight enough. Also I think it has to be connected before the truck is started or "on" as there are times where I have got the connection tight but needed to shut down the truck before it would recognize the camera. I did move the camera/7pin up into the bed as I have a 5th wheel.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
