Steering Wheel Module?? B7 A4
 

Hi, I recently purchased a B7 A4 2.0T
The car is multritronic and the steering wheel did not have the radio controls or the f1 shifters
I purchased an "S" Steering wheel that has the shifters and the radio controls on it
I heard that there is a module that I need to install in order to make the radio controls work. Where can I get that module? Will that thing make the shifters work too?
The most important thing for me is the shifters. How can I get them to work? Thanks...
