I have two of these. Consists of doc for the pc, phatbox, cartidge (20 gig) and lead from phatbox to cd changer lead.
All you need is a 12V adapter (i only have one of these which i got from maplin).
One is boxed with the brackets
Both excellent - no scratches and Audi firmwared..
80 quid plus post a piece - just looking to shift.
