Just a quick note to anyone who has a V35 skyline with the built in rise up monitor, its a whole lot easier to move the nav dvd unit behind the passenger kick panel, just takes a bit of time and some wire extending, you also need to do some testing to find the correct wires to cut so you can use the dvd while your driving, on mine it was the purple and orange wire (hand break, which you need to connect to a ground and speed limiter cut off). once you do that you can fit a dvd player in that spot, ofcourse you need to hook up the wiring to the signal box in the boot (thats where mine is) so you can hook up the dvd to the screen. if your handy with a test light, screw driver, wiring and soldering you can get it done in a weekend.. there are a few diagrams on here which show you the wiring for the tv signal box, just have a search and you should find it. i think this way the car looks cleaner, less modified, less head ache and certainly less expensive on the pocket, you can get this done by alot of people around sydney now but they still charge in excess of $2000 - $3000 which is a bit of a rip which is why i did it my self and i could not have asked for a better result..
hope this helps make things easier...
