Hi. Just picked up a pre-owned '12 G37, and maybe someone could save me a few minutes. My NAV displays interstate highways as state routes--i.e. instead of saying Interstate 85, it calls it State Route 403 (which it is, but nobody calls it that), both on the screen, and during navigation. How do I fix that? Thanks.

 

Pretty sure you can't do anything about that. It'll display whatever is stored in the map data.

 

Go into the map settings and make sure the current maps are set to your region in the country.

My 09 coupe is from New York and when I first got it I had trouble with my maps. Setting mine to the proper region (south east) helped.
