Hi all,I have a ps2 install using rear necvox headrest monitors to For visual but I don't have any audio. I think this was a bmw install when car was new and was wondering should It be hard wired into the cars speakers or does it use headphones only. I have found a remote wirless unit for headphones in the rear cubby hole along with a hirschmann car tv unit but don't have any headphones with the car and the one hirschman remote I have does nothing. Any ideas people?

I had something similar in a previous car and the headphones took an Infra-Red signal for the audio.  Do the screens IR transmitter(s) or is there an independent one somewhere around, say at the join between the side trim and the headlining?
Good luck!
