This is probably a very silly question..but I'm pretty clueless where mobile technology is concerned. My last car had an integral phone with all the gubbins. I'm about to pick up my A3 that has the GSM phone prep. I know it works off bluetooth (or the extortionate cradle) and can be controlled through the steering wheel. But does it have a microphone anywhere in the car. I refuse to wear one of those Alan Partridge ear things, so the absence of a mike in the car might prove a bit problematical.
