I need to know if a Audy Symphony II In-Dash CD-Changer from a 02 or 04 A4 or S4 will work in my 01 A6. The wires look the same, but I was just wondering. Didn't want to buy one and then it not work. I have a bose symphony with in-trunk 6 disc changer but it doesn't work right and want to replace it. I could eliminate the trunk changer with the new head unit. Thanks - Steve
