05 porsche cayenne Intergration

has anyone intergrated anything into these yet....i am getting ready to do a full install......any tips would help......one thing i am REALLY not certain of is if head rest monitors are possiable.......that is one thing that my customer was wondering for sure about.  I plan to intergrate a composite to RGB converter into the factory navi screen .....change all speakers......5.1 dolby surround sound, remote start and security if possiable,  and a small sub and amp .......all off the factory deck.Where theres is a wire there's a way.

I put an overhead TV in one so I know that's doable, but can't remember what the headrests look like offhand. The vehicle is basically a VW Toureag the radio would need the new style VW antenna adapters if you plan to add anything FM modulated.
