I am going to Purchase a HTC Touch Pro phone and since it has a video out I wanted to use slingbox and hook up a lcd monitor in my car so I can have direct tv in my car. I have a monitor but the Aux input only has 1 port looking like a headphone jack, if I would buy a Female to Female RGB adapter would it work? I also thought a Plenio VXA 3000 would work since it already has a FM transmitter, any sugestions would be very much apreciated.

Thankyou!
