I've just bought a mk4 golf which has a knackered old kenwood head unit, I just want to replace it with the original VW head unit and in dash cd player. I've purchased said OE items from ebay but on taking the kenwood out of the dash I discover a mess of chopped wires and when I plug the VW head unit in it doesnt work
There is an ISO adaptor plugged into the orignal ISO plug for a parrot handsfree and then another one plugged into that for the kenwood but even when I remove all that and plug straight into the orignal adaptor it doesnt work.
On closer inspection the original ISO plug has been chopped and a different one reconnected in it's place (all the wires coming from the new plug are different colours to the original) and the original 2 red/white power wires aren't connected just the yellow/red I've found a diagram showing which wire should be connected where but can I buy a new plug from somehwere or just reconnect the wires in the right order (but to the worng colours!) and will this mess up the hands free?
