Guys & gals, Seen alot of threads regarding this issue and just want to know what is best. Harmon Kardon/ Dansion or Audi connection? Have just picked up my new A3 just over a week ago and want to add this feature but Audi have quoted me £230. I want to know what costs £230 especially now I've read other user reviews on what functionality it gives you. Also does anyone know a good place to get it installed in and around the South East area of London/ Kent. Your help would be appreciated and I know there are already a number of threads on this site regarding this so sorry!!
