Can anyone recommend anywhere to go to have a decent car radio installation done for my Audi A4? Someone with experience that actually knows what they are doing with Audi wiring, ie not Halfords etc. I'm looking for someone around SW London preferably. Got a Concert II HU which i want to replace with a HU that can supply DAB, any recommendations for what to use? I have BOSE and factory fitted phone handsfree kit and a MFSW that i would like to be able to utilise still. Am i right that DIS display can't show radio information from any other radio manufacturer?
