Thought this may be useful as I couldn't find any posts with pictures when installing my stereo.
From my local shop I bought - an Autoleads facia, quadlock cables inc. steering controls & an amplified antena adapter for approx. £70.
Cables were fine but I found the Autoleads facia not to my taste as the headunit sits about 7mm in and requires use of the headunit trim kit:
So I decided to buy the Connects2 facia kit CK23VW07 which at £49 is not cheap but I felt looks much better:
While buying the new facia I saw that Connects2 sell a kit which includes a similar facia (flush fitting and doesn't require the use of the headunits trim kit) and all the cables etc for about £70 (CT23VW01 I think). Far better value than the £110 I spent all in :( oh well live and learn.
