I recently installed my Z100BT. I have been receiving complaints when using my cell phone through the bluetooth connection. While I can hear the person on the other side crystal clear through the systems speakers, the party I am talking to complains that they hear a loud constant wind noise while my vehicle is in motion. When my vehicle is stopped, the wind noise is gone. The noise is not coming from the vehicles a/c as the wind noise is the same when the a/c is off. Does anyone have any ideas what and where this wind noise is coming from or the quick fix? Thanks.
