Hi all, I got a Volvo DVD to update the Denso NAV on my '08 XKR to 2017 mapping. My question is whether I can now update the software on her '14 XJL with disc A?

Furthermore, if we take a trip in the XJL, can I swap the Disc B from the XKR to the XJL without blowing anything up? While it sounds illegal, it would be handy to know the answer.

 

Nope, the X150 (XK/XKR) and X351 (XJ) use different systems.
