Thanks Ed, much appreciated.
I decided what the heck and fitted it earlier before I went out. Problem is, the CD multiplayer in the armrest won't work. When I switch to Aux, it makes this awful sound, no music???? I did change the pins over, yellow to pin 1 and grey to pin 7. What could be the problem?
From the images I have seen, I did have a few more wires than in the pics though.
