What do the four icons on the screen of the GPS mean?
The top, right icon shows whether or not the GPS is locked on a route. When you see the blue arrow, the map is locked on your route. If you use the + or – buttons (Zoom In and Zoom Out, respectively) to change the zoom level on screen, the view will revert back to the default route view after three seconds. You can toggle between two different views with this icon. If you click on it, the top icon will change to a “folded map”. This mode will allow you to scroll around the map freely, which could be useful for referencing future turns or navigation events. The bottom, right icon also changes the map view. There are three modes: Facing north, marked by an “N” in a triangle, 3D marked by a three dimensional arrow, and 2D marked by a flat two dimensional arrow.
