How do I interact with the map?

Zoom:

Nyon offers eight fixed zoom levels. In Map & Navigation mode, these can be activated either directly by pressing the joystick or via the "zoom in/out" submenu.

Switching between 2D and 3D:

There are two options for displaying maps in Map & Navigation mode: 2D and 3D. The map display can be set separately for map mode and navigation under  Settings > Map & Navigation > Map display.
