Apparently there is an audi microphone that fits into the light console in the cabin that can be used with a car kit. I'm thinking of getting the xcarlink kit for iPhone with the bluetooth module. The kit comes with it's own mic but it will have to be fitted somewhere. I was thinking that I would just get the Audi one and tuck it away in the light console an plug it into the xcarlink. Does anyone know anything about the mic from audi or even have the part number?
