Ok specs:

1999.5 a4 concert audio

I have the same center console as 2000-01 a4's. So I know the symphony I will fit physically in my dash. But what I want to know is will it plug in (same pin outs) or is there an adapter, or would I have to custom wire. Or am I completly off my rocker?

I like the look of the symphony headunits better and I like the cd function up front. I did the search deal and found nothign that helps.

 

Nevermind Im just decided 100% to go phat noise. But Id still like to know if its possible.
