Sorry I know this has been covered lots of times, but I'm getting very confused.
I have just got myself a used BT module for my A3 8p MY09 SB S-Line.
What I'm confused about is the plug and play wiring harness, I have seen loads all different and costing from £12 to £25. I know I will also need the mic, but after doing a search and giving the part number to my local dealer I was told it's the wrong number. So what I really need is the following.
Link to the correct wiring harness and Part number/link for the Mic
I know it will need coding so will be looking for someone local with the knowledge.
Thanks in advance
