Gentlemen, I have just today bought an x5 3 litred diesel sport (reg 2002). The dealer advertised it as having sat nav but when I checked the screen out (it has a tv on the console that works etc), I noticed there was no sat nav menu. I checked in the boot/trunk and noticed that the only unit sitting there was the dc multichanger. Can I buy a unit? And if so, what unit should I buy, how do I fit it etc.

Any help greatly appreciated.

Thanks
