I have a '03 XK8 with the original sat nav system. I must not have the last release of the sat nav DVD because the display shows the leaper. I'm trying to find the version that shows the clock face instead. My DVD is Jag P/N: LJE2441GB, Alpine P/N: BM9JU91C. Please correct me if I'm wrong, my research indicates I may need Jag P/N: 4W83-10E898-GA, Alpine P/N: BM9JG91F. Any assistance would be greatly appreciated.

 

I may be wrong but I think the number beginning 4W83 is the Denso system on the XJ range which wouldnt work with the Alpine system. But in any case try this site they may have what you need. I found the latest one for my 2004 XJ8 there.

I have the latest satnav disk (shows the clock) out of an '05 XK8. PM me if you're interested.
