Anyone know how to use the Sierra AT4 surround view cameras to record vs buying dash cams. I have a friend with a Cadillac and there is a sd card slot in the trunk for this. Why didn't GM add that feature to the Trucks

problem programing Homelink on 2024 GMC AT4. Homelink Rep phone response 1. Went through homelink/GM programming procedures for Chamberlin Liftmaster. Bothe handheld remote and "learn" button: Didn't work 2. She said remove LED bulbs from Garage opener, LED can interfere with signal. Didn't work 3. She said the hand remote I had, probably an aftermarket from years ago, was not compatible with homelink, I'd need an actual Chamberlin Liftmaster remote (haven't gotten one yet) However the remote I have works the garage opener perfectly so not sure why that's an issue. I have a 2021 Lexus that programs immediately using the learn button I had a Ram PU that programmed immediately using the learn button So I haVe a 70k (MSRP) GM vehicle that the garage door opener won't work.. very disappointed in GM
