Yes I have bought the usb part and silly money £170.00!! From HERE Technologies in Holland.
The trouble I have had on my 2010 is when I plug in the usb it does nothing! this seems to be a design fault from Jaguar!! My car is going into a dealer for them to have a look and Jaguar will foot the bill as it is a design fault? This only seems to be on the early cars?
Good luck
