Again, use the up and down arrow keys to move the box to the desired

Map 300 returns to the AirMap Options menu.
Map Orientation
Normally, the AirMap 300 shows the map with north always at the top of
the screen. This is the way most maps and charts are printed on paper.
This is fine if you’re always travelling due north. What you see to your left
corresponds to the left side of the map, to your right is shown on the right
side of the map, and so on.
However, if you travel any other direction, the
map doesn’t line up with your view of the world.
To correct this problem, the AirMap 300 has a
track-up mode that rotates the map as you turn.
Thus, what you see on the left side of the
screen should always be to your left, and so
on. It also has a course-up mode that keeps
the map at the same orientation as your initial
bearing to the waypoint.
