Our 2017 3811ms came with one. The fiver had a camera on the back of it and the truck camera that pairs with the camera on the fiver was in one of the drawers. It is much easier with two people to pair the units once you get yours. One person pushes the pairing button on the camera in the truck and the other pushes the button on the camera on the back of the fiver. Also, ours is wired in the light system so the headlights must be in the on position. Ours won't work in the auto head light position. Hope this helps?
