I have a Nexus Sat Nav unit in my 56 plate Octavia which can apparently receive audio and video signals (sound and picture). I can send audio to the unit with the aux in, thats is inside the central console box, using a std double ended 3.5mm audio jack, how do i get video in though?

I can't even get the audio to it using aux. How does it work.??

Perhaps this will help.

At a guess, it will need coding with VCDS as well to activate the video input.
