Hi all, Now I'm not really an audio man so need help! Want to replace my Audi symphony unit with a double din Sony, went to halfords today (should of gone to a car audio shop I know but as its Sunday none were open) spoke to the audio man at halfords and he couldn't really help that much, he said I will need all these different harness adapters first to wire the stereo then a Sony adaptor and one to make the steering wheel controls work! Someone please help and let me know what I need! Just want a decent head unit! I have the non Bose, half amplified system! Cheers. I'm sure this thread is on the forum at some point but there's so many to go through!
