Navigation system

Yes, I don't have a manual handy, but if you look in the manual for the navigation it's an easy process to find out what version you have. I beleive version 12.1 is the current one.

there should be a settings menu and an 'about' section, or something similar. That should tell you which nav verison.
Your 2012 is entirely software based, so there's no dvd to look at.
