from jaguar but these are exspensive, or a jaguar breaker. there are also some on ebay, but dont forget you will need the d2b fibre optic link cable as well, what options is already fitted to the car ? sat nav, bluetooth, voice. these also run on the fibre optic d2b network in the x type. the power cable for the cd changer will be wrapped up in the near side rear boot area. you will also need the cradle to hold the cd changer , but if you have sat nav, bluetooth or voice then the cradle should be there. hope this helps you out.
