I just added a double din to mine. It has ports for both front and rear cameras. I did a video to show mounting and wiring of Double Din Stereo operated forward and rear cameras on a 2006 Jeep Wrangler . Took it offroad this weekend and I love the cameras. The Apple Carplay is awesome too. Used maps to track the trip. It was nice to know distances to waypoints.
Note1: the hole I drilled by the hinge is 1/4" - too small for the RCA connector to fit through so I clipped the wire and reconnected it after I passed the wires through the hole. I probably could have drilled a big enough hole for the connectors to fit through and still be hidden by the trim, but I just used the smaller hole.
Note2: I bought two backup cameras. I really needed one backup and one front camera because a backup camera reverses the image to be the same as looking in a mirror. A front camera does not reverse the image. I replaced my front camera with one made for the front.
