Hi everyone, Today I realised that there is a bluetooth option on my '06 a3. I did pair my phone (nokia lumia 820) to the car, it accepted it, I am even able to scroll through the contact list with the knob on the wheel. Howerever, when I tried to call someone it doesn't seem to work properly. Dis shows that it is calling (shows number) but there is no ring sound before the call and once someone picks up ithere is no sound whatsoever. I checked the phone during the call it says bluetooth option. I am not yet sure if the otherside hears me. I think that there might be something wrong with the settings, or something with 'mute', or compatibility. Any help is appreciated! One more thing, the button on the steering wheel (right side) says speak after pressing it. What is the use of it? Cheers!
