Comes up at ~£150 on Lings; I couldn't find it listed on Cox but it may be worth calling them to see if the forum discount knocks it down a bit.
Brilliant, cheers Haltamer - I never thought of Lings. I emailed Cox a while back but they said they only cover parts that originally came with the car. Out of curiosity, have you used one of these yourself? I have a single-din stereo, do you think it would fit with this? I'm sure I could find a pocket somewhere for the remaining gap.
