I have just bought an 2004 Audi a3 SE Tdi 2ltr. I have worked out the majority switches and buttons, however, there are 2 buttons on the steering wheel that have me baffled. One is the Mode button (inner LHS), the other is on the (inner RHS) funny ))) symbol. The manual identifies these as mobile phone functions. When pressed the screen displays No Funct. My question is; do I need to buy an extra gadget to connect my phone to use these buttons or do I need to upgrade my concert radio use these buttons?
Any advice gratefully received
