So which wires are which?
I still don't know what they all are, but very simply...
ISO -> Quad-Link wires as below:
BLACK -> BROWN
RED -> RED/YELLOW
Then connect the YELLOW wire into the 2nd RED connector from the stereo end, which just bypasses the ignition (as I haven't found where the ignition wire is). This means the stereo always has power though, even with ignition off.. So not perfect, but working.
I don't think the BLUE wire on the ISO is needed and I don't know what the 2 thin orange cables on the QUAD-Link in the car are for.. The old stereo has a diagram on it with something like CAN/H and CAN/L but not sure what this means.. Also there are the 3 cables going into the little blue bit at the top of the Quad-Link which are not in use, but these might be something useful..
Just need parking sensor to go somewhere so I can change some settings.. haven't seen a DVD playing yet, as screen keeps going to sleep after 5 seconds.
Things still in the post are aerial adaptor and the VW facia. Can't believe its taken over a week for them to arrive! Stupid Bank Holiday..
Any extra info would be great!
