There is also the bluetooth speaker that is attached to that unit which I have no clue as to where the mic is located. and dont forget the little shark fin on the top of the car. So to make it work you would end up spending more money than just purchasing it in the first place. I would suggest going aftermarket or if you really feel you must have the nissan system trade yours in on a model that has nav. I hope this helps.
