as long as you have a video source (DVD, PS2, whatecer) You only need ot get a monitor, flip out screen, or whatever you want to display it on. Then you run the video out of hte device to the video in ont eh monitor. the audio is played thorugh your stereo.

Or you can do it easy the first time, get a flip out liek a clarion, pioneer, kenwood, and be able to add TVS with only a video line.
