Bluetooth Problems with my w910i and my Ford

Hi All,

My phone has been fine since I've had it (about 3 months) but I've now just got a car with a bluetooth audio system and it works fine in it. The issue that I face, is that when I remove the phone from the car and disconnects from said bluetooth system I am unable to hear anyone through the phone ear piece. If I change the call to speaker I can hear the person fine via the loud speaker. Same receiving calls and making calls. If I turn the phone off and back on - it works fine. Have recently updated phone to newest firmware.

Anyone have any ideas?

Thanks
