Not sure if this has been covered or not, but I just installed an OEM factory rearview mirror cam on my 2021 Tahoe PPV. No programming needed. One check engine light came on when I swapped out the whole unit. It apparently needs the original reverse camera or it throws a code. My rear view window is so heavily tinted, I needed this. Gotta admit, pretty cool. Just an FYI post in case anyone else was curious about codes or compatibility.
