Hi all, I have a fl2 xs on a 59 plate with sat nav.can anyone advise me if I can upgrade this system to a multimedia system including sat nav and usb.all advice would be greatly appreciated.

I don't think it's possible..

Firstly I don't understand your UK registrations descriptions to identify your model.
Secondly, Yes you can there is plenty of aftermarket systems available to do this on ebay/Aliexpress that are designed for Freelander 2.
If you want the OE system then how big is your wallet, everything is possible at a price.
Good luck  MY15

Registration marks in the UK comprise two letters, two numbers and three letters. XX00 XXX. THe first two letters identify the area of the country that the vehicle was registered and the last three letters are just random letters.

The two numbers identify the half year in which the vehicle was registered. The half years run 1st March to 31st August and 1st September to 28th/29th February.
