My phone is paired with the car and it works really well for me when I am driving. However, I have had several people tell me that they cannot hear the passenger when they are talking. Yesterday, my wife was driving and we were talking to my dad. He kept saying that he couldn't hear me. I finally leaned over toward my wife (the driver) and then he said that I was coming through fine. Is there a separate microphone for the passenger? If so, then mine is not working. I can't find information on the microphones in the Owners manual. if there is just one microphone, are any of you all having difficulties with it picking up the passenger talking?
