Multimedia systems are your passage to fun on a trip. Install a screen in the headrests to give each passenger choices like a TV station, DVD or game to watch. Headphones allow everyone to listen exclusively to the happenings on their screen. You can also install an overhead screen, which can be much larger (and visible to everyone in the back seats) and can accept an auxiliary audio/video signal, such as a camcorder or digital video player. Everyone gets to enjoy a video on the go!
