Sorry for all the postings in the mk4 forum but just got my first Astravan and Im trying to sort a few things on it!
Basically, I have the standard CDR500 radio/cd with the steering wheel controls and I want to fit a spare head unit I have lying about which is a newish Sony Bluetooth/mp3/handsfree thingy.
Whenever I've put head units in all the VW's and Audi's I've had, it's just simply been a case of unplugging the old one and plugging in the new one using standard ISO connectors, but I have been told that in the Astra I might need a wiring harness/adaptor to fit the new stereo, is this correct? If so which one??
I realise that by fitting a different head unit I will lose the controls on the steering wheel and also the display on the top of the centre console but I'm not concerned about that.
