Just a note to say I took my Symphony II radio/changer out to fit an aftermarket HU but decided it was too much hassle! the stock radio was disconnected from the car for over 24hrs and needed no code when plugged back in, someting to do with holding it within the car can-bus system

So you only need a code if you are changing radios over.

Mine is a B6 2005 btw
