Whats the deal, after reading various websites and forums can i easily swop my oem head unit for a new aftermarket one, or does the multiplex wiring stop me from doing this? do all 307's have this type of wiring? Very confused!! i have a 2001 307 hdi d turbo 110

Your car is immune to this mutliplex wiring system, although If you have steering wheel controls and you change the unit, they won;t ever operate again.

If for any chance that the FRENCH may have multiplexed your HDi then fitting an aftermarket unit is more trouble than it;s worth.

What' bran is your exisiing system , blaukpunt, or some other braned peugeot unit.
