g.u.

I'm seriously considering to upgrade our 2016 2500 Denali to the 2020 model. I was told by the dealership that the "smart" rear view mirror can only display the feed from the bed truck camera - as I will have a cap that's not much use. Ideally I would live to have it display the trailer camera feed instead - in fact I believe it would be much better than having it on main screen which I'd rather use for nav. In fact, invisible trailer looks cool but not very practical as it takes over the whole display and you'd need it on pretty much all the time whole trailering. The software may not allow it (dang, why?) but I can't see much harm in switching cables assuming it's possible...
