It should come with a portable unit for inside your truck. With that being said if you got the correct option on your new truck you should be able to program the camera to your built in screen. I am currently doing research on what all options I want if I buy a new truck and if I read correctly that is part of either the tow technology bundle, rear chmsl camera or the ultimate trailer tow camera system. Sorry I can't do better at the moment but I am still trying to figure it all out myself. They still need to give you the unit that comes with it. Mine used to only work in reverse but it has been rewired to come on with the lights on.
