Cameras and trailering app help

[Tfkkolar]

2024 2500HD LT. At night all my cameras are useless. I have to step on the brake to get enough light to see in the camera. Daytime is perfect. Its almost like there is no added light for night time use. My 2021 worked great in the dark. Also can not get the jack knife or trailer length indicator connect. Keeps saying drive forward to calibrate but never connects. Trailer presure sensors installed and work great. Advice?

Are you talking about the invisible trailer option when using the GM camera that you mount on the trailer? I am having the same issue with my 2024. I havent persued it very hard yet but need to dig into it hard the next time I hook my trailer up.
