I don't think satnav was standard on the 2014 model of SV6. Even on the Calais it was a $700 option (although it was standard on the Calais V). If your MyLink controls don't have a button with 'NAV' on it, you don't have satnav fitted.
you can tell if you have the navigation version of mylink by looking at the buttons/dials.
on the left side of the mylink buttons just above the round tune/menu dial the navigation ones have 2 buttons "dest" and "nav" and the non navigation units have "fav" and a play/pause icon.
