Ok guys i have a factory nav want to hook up a aftermarket dvd player 2 play in nav and headrest what all do i need wiring...thanks..

 

wtf.. know buddy knows anyone.. come on

 

nobody may know what you mean..stock nav on what model lexus?..if your in the is250/350 area you must buy the ML DVD player (try car-part.com), custom harness which me or a member i taked to can get you to connect to stock nav..as for headrest monitors..well if you want to cough up 800$+ for a custom built output on the stock system GOOD LUCK! i may be doing this but with all the $$$ involved may just go all custom flip-outs n so on..quick output connections, easier wiring etc.
