5.7.4 Direction Dial Screen
The default navigation mode is the Direction Dial mode:
The direction dial includes an arrow, which always points in the
direction of the Target you have selected. This is the bearing to go.
The triangle at the top of the dial represents your current direction of
travel (your heading). This triangle never moves, but by moving in the
direction of the arrow you can line the arrow up with the triangle.
When the two are aligned, you are heading in the direction of the
Target.
Note – Since the Direction Dial and Road displays are calculated from
the direction of movement (heading), they will not be correct if you
move backwards.
The four Info panels can be configured to display relevant text-based
navigation information next to the direction dial. the&
Press
softkeytodisplaytheNavigation options form where you can set
options, including the Info panels, for both graphical modes.
When you move close to the Target, the bull’s-eye appears on the
edge of the Direction Dial screen, in the approximate location of the
Target. This feature has two purposes: to guide you more exactly in
the direction of the Target, and to warn you that the display is about to
switch to the Close-up screen.
