Got my 6 Plus on release day and the Plus Bluetooth worked great in my Ford Fusion. Today, out of the blue (no pun intended), phone calls stopped working. Music plays just fine.
What usually happens now is I can initiate a call, but it cuts out after a ring or two and says "call ended". Sometimes, the call won't end, but no sound through Bluetooth, only speaker and phone.
I've deleted the link to the car, and deleted my phone from the car. Rebooted phone and turned the car off and on again. No joy.
I've read that "Resetting All Settings" may work temporarily, but I'd hate to set up all my settings and just have it fail again.
