When I call using bluetooth, the party on the other end hears me like I have wind blowing all around me. It happens at any speed (including stopped in a parking lot). I have tried pairing it with a headset and still get the wind tunnel effect, but is quieter than in my car. I do not get this effect when I use my Droid RAZR MAXX. Has anyone else experienced this? I am leaning towards it is the Icon and it has a bad bluetooth antenna or some other part causing issues rather than a general failure of the Lumia line and Ford Sync.
