Maxima Forums - Is There Anyway To Convert The Navi System To Play DVD's As Well In An '04 Maxima???

....I've heard several answers to this. The place where I installed my Clifford alarm and did my tints told me that there was some sort of module out there that enables the navigation system to be used as a TV/DVD as well. In some other shops I've heard the exact opposite. I'm considering in converting the navi system into a TV/DVD if it's possible but if worse comes to worse I'll just put a flip down on the overhead panel (sunglasses compartment).

I've also though of actually doing a customizing job on the actual center panel (where the stock radio, cassette player is located) but I've been told by doing that it will void the warranty. Anyone knows anything about that??

Thanks in advance.
