Hi all, I'm looking to swap out my standard double din bose head-unit on my a4 avant s-line, for my pioneer avh single din hu i had in by b6. After lots of searching and a few phone calls to car audio dealers i'm looking at using Connects2 ctkau09 full fitting kit. My question is has anyone had any experience with this kit? I like the sound of the bose system and dont want to loose any quality in sound or get any annoying whining or hissing sounds as reported by a few people when using other adapters. Any advise would be greatly appreciated before i order the kit.
