Hi I have an audi a3 tdi sline 170 on a 07 plate. I want to replace my double din cd player to a standard single din alpine bluetooth cd player. What adapter harness do i need as my original unit has a quadlock plug and a twin aerial connector. It is not a BOSE system either.Thanks
 
Look for a CTSA-D002 it comes with steering wheel controls, but if you dont have them dont worry just plug it all together, will do your illumination, and ignition. Only if you have half amplified speakers, if you dont im not sure, but someone will come along and point you in the rigth direction.

In regards to antenna it depends but you need an amplified one. However on my Alphine i didnt need anything extra all works fine for radio.
