Some info from Pete.
------------------------
Open the ash tray and there's a screw at the top. Then when you take the ash tray out there's two screws behind it. Then pull the HU out and remove the two screws you see at the sides. Then the front facia comes off the clips. The air con control is then screwed in with 2 screws.

Thats a good price, even £80 would have been cheap. They are at least a couple of hundred new I think.
