It does have 2 cameras but it doesn't have the software for the other views. Sucks I know. I have the 2021 elevation Duramax as well. Sent from my SM-N986U using Tapatalk
You should be able to just unplug the button from behind the dash. I've already had mine taken part already to install the auto start/stop kill and it's not that difficult. I may actually do this. Sent from my SM-N986U using Tapatalk
