I have a Symphony II+ head unit in my 2007 A4, here is one of the only pictures I can find of it.

I have searched through over 15 different Audi Forums (I'm sure there are more) and cant find what I'm looking for. I few hints...but to prize.

Basically I'm looking for a wiring diagram to I can hook up an AUX port.

I have read that this new hard unit has pins in the back specifically for an AUX port and a spare CDC plug I can use an IPOD or something.

I have a Sirius Stiletto I want to direct connect (RCA) to the Aux port but cant seem to find what pins to use. I guess I can either use the CDC or AUX but if both are there...I want to use both...

Can anyone help out?
