I have tested various Moto phones in the last month. I use mine in the car with the bluetooth connected to the car stereo.Recently it is no longer routing the phone audio thru the car even though its connected. When I click the gear icon to check the settings while
its connected the check box for "Phone Audio" is unchecked and will not let
me check it!
As I was checking my Bluetooth settings, and I turned off the scanning settings for Bluetooth. After turning it off, I was able to turn BT off then on, and I did not lose my Audio settings.
