Hi
you pair your phone with the phone bluetooth module to make calls, you can't pair your phone to jaguar voice, you make commands through jaguar voice, but your phone must be paired with the bluetooth module
the usb socket in your car is part of the parrot system, it enable you to use a flash drive and play music off it through your parrot hands free system
some jaguars do have a usb and ipod connector in the arm rest and that is the ACM audio connectivity module, this allows you to play music through a flash drive and ipod through the jaguar speakers and can be controlled via jaguar voice
cheers
Joe
