MY 2004 XKR has a factory installed Alpine Electronics navigation system. The information contained on the disc is dated 2002/2003 and much of the information is obsolete or missing. I have called the Jaguar dealer and they said that Jaguar quit using Alpine in 2004 and changed systems in 2005 and there is no updated version for my car. I think that they didn't try very hard to find out. Does anyone know if there is an updated disc available for my navigation system?
