When talking on the phone using hands free, only the driver can be heard clearly by the person on the other end. The passenger cannot be heard clearly making me think the overhead microphone on the passenger side is not working. When I told the service people at the Mazda dealership, they said there's not a passenger side microphone, only one on the driver side. Can someone please confirm if there are one or two microphones on the overhead light switch console? It looks to me like there are two. Thanks!
