Hey everyone,
I have an 08 Audi A4 Sline came with a multi function steering wheel and the audi symphony ii+ system. When I press the mode button it states no Function and also when I press the BT button still no function. Volume works fine, and the scroll wheel on the left works to change songs and radio stations, which I assume is correct.

Now the non functioning part from the reading I have done I need a BT module and a microphone correct? What are the part numbers for these? I found a thread with some part numbers but I am not sure if these are US only? As I am locataed in Canada and am wondering if they would still work, not sure why they should not be able to? Can anyone point me in the right direction for the proper installation of the Mic and the BT module? is this even possible?
