No, it requires an external sppy to switch the unit.
The additional chip is a sync seperator which is being used to extract the requried synd for the sharp LCD display.....ow yes, its obsolete to!
Sorry Mark,
If this answer is aimed at me; I don't understand it?
I'm not up on electronics, sorry
Is it possible to have a DVD which outputs to screens in the head rests and to a manual switch, which when opened allows that same output to show on the CID and override the SATNAT output?
I only reckon I'll understand a "yes" or "no" in answer to this question. If it is a yes then I'd be interested in pursuing it as a potential option, if no, then I'll go back to sleep.
I'd still need to find a suitable way to have a DVD player somewhere in the car without losing my standard fitted Bose head unit. I want to keep that because I like the standard look, the SATNAV and the computer functions on the dash.
The more I think about it, the more I realise I may be barking up an empty tree here.
