Traded my 2019 Sierra 3500 in yesterday for the 2020 version. Definitely interested in the cameras. When I was at the dealership this morning to get a couple of things I forgot from my old truck, I asked about the invisible camera and a camera inside the trailer (we trailer horses, so an interior view of our horses would be great). Guys in parts didn't know, so he called the manager at the local GM parts depot who got my VIN and looked it up. He called me back and said that they had the cameras in stock and I mentioned that I have a 49' long trailer and he said it would work with a bluetooth extender.
So, now I'm trying to figure out if the camera setup is wired or wireless. Seems to me that the OEM cameras are wired - did he have his parts or my truck mixed up with something else?
The quote for 2 cameras with install was $1310.
