Can the x351 XJ be updated by Disc, or does it have to be by USB?

I found this Disc which seems to be for an XF for 2016, just wondering if it will update my 2010 XJ?

2016 Jaguar Sat Nav Update Discs

What site has the cheapest option? Anyone got a Disc/USB that has the 2016 maps on them and is willing to sell?

 

I think you're out of luck judging by the web page:
Only for DVD based satnavs!
The navigation reader with your current disc located in the trunk!

NOT for the facelift HDD models!

 

The X351 XJs have all been hard drive based Navigation and can only be updated using a USB flash drive aling with the unlock code provided on the purchase receipt. IMO

 

Thanks guys, anyone know of places where people sell the USB updates for satnav, even second hand?
