I just bought a 2024 2500HD Duramax. It currently has just the backup and trailer hitch camera. Does anyone know what would be required to upgrade to the multi camera. I found find multi camera control modules really inexpensive on eBay, just not sure what else may have to change. Is it as simple as replacing the original control module (likely need to be programmed to the vehicle) and installing the desired Camera. I know of aftermarket systems but they are "clunky" to operate. Has anyone done this?
