2005 Lexus Rx330 Dvd Video Output Signal Location (from Navigation)?

[shortdahri]

Wanted to install a set of Vizualogic headrest monitors but wanted to run DVD movies off the factory navigation unit to these headrest monitors. I figure its easier for me to just throw in a DVD for the kids while driving rather than stopping the car and going to the back.

I've searched and only found information about displaying a DVD movie on the front navigation screen.

Can anyone tell me where the video signal output wires are for the factory navigation unit? I need these output wires so I can provide a video signal to the headrest monitors.

If there aren't any wires available, can anyone tell me if there is a converter or adapter that can make a video signal available for this install?

Thanks in advance guys. My kids thank you too!
