As the title says, I have no problem pairing the phone, downloading phone book and all other settings. As soon as I initiate a call, "Bluetooth Disconnected". I have to use the phone. As soon as I hit END, "Bluetooth Connected"

I have the Ford Sync with touch screen. I just paid to have the Update installed from Ford. Same things. My old Razr worked fine, wife's Razr HD works and so does my daughter's 5s. My phone works fine in my wife's GM and my work Jeep. No one has ever heard of this according to Ford and Motorola.

I have disconnected the vehicle battery already, phone reset to factory, phone replaced, Ford Dealer installed Dealer only update and reset complete system to Factory.

I have searched and searched and searched. Anyone have any ideas?
