Just a quick thanks to all that post on here!
I wanted the option of a cd changer but like to keep things looking factory so after a bit of mooching about on here I now have a 6 cd changer in my glovebox, and even better it's only cost me £50! Got the changer from a guy on ebay, (came out of an Octavia but same part) and bit the bullet and paid £20 for the genuine lead from Audi. 40 mins later, sorted!
Only thing I need to do now is Tractorman's mod on my glovebox 'cos my liner ain't the cd one
