In the 2013 Limited version, there is a gray square icon near the bottom left corner of the Nav map screen. There are three modes/displays. Push the icon to rotate through the three displays.
One icon looks like a yellow route going through a city - part of the route is behind a building. This is the 3-D map display with the top of the screen pointing in the direction of the car.
The second icon looks like a route going through a flat city. This is the 2-D map display with the top of the screen pointing in the direction of the car.
The third icon has a compass star on it. This causes the top of the screen to be always oriented north. I find this mode difficult to intuitively understand.
It is also buried in the menu system.
I like the 3-D mode.
If you do not have the same version of Nav, it must be something similar, perhaps in a menu setting. Good luck.
