Probably the easiest HU install I've ever done. Maystar fascia fits like a dream and matches perfectly. The BP Woodstock 54 has all the same bizarre connections as the original Audi HU (mini-ISO), although I did need to ad a few pins to the power ISO. The aerial was also pretty easy to run round the headlining. Now all I need to do is work out how to drive the thing, can only seem to get 80's pop channels at the moment, oh and 5live in glorious digital quality, what a difference.
