F****d volume on the Concert so I'm getting a Chorus one fitted tomorrow. Most features work but the lights for the controls don't so hopefully the radio shop will solve this problem. The Chorus is from a facelift A3 but mine is an original style A3 so there must be some slight differences in the wiring of the iso connector. I'll let you know how it goes as this could be an alternative to buying over priced Concerts off of ebay. My Chorus was £40 ish from ebay so a bit of a saving. Cheers, Deano.
