How do I get the 3D view to work on this GPS? The part where it goes to the split screen when your taking a certain exit? Does that feature have to link up through a smartphone or not? Thanks!
This function is automatic. It will not come up at every exit, but should at most in major cities. We add more each time map updates are released as well.
