The Ford Sync system of mine is kinda different. It gives you a 6 digit code which the phone won't accept. If however you dial a knob 1 click to the right and then press OK the radio display shows "Use Special Code" and you press OK again and it diaplays "Use 0000" Enter 0000 in your phone and ur good to go. Took me a couple of tries though.
I know you don't have a Ford but the system may have been designed by the same idiot
