Head-up: Displays the chart with the current compass heading of your boat at the top
of the screen. The heading data from a compass is required. When the heading
changes, the ship icon remains fixed, and the chart picture rotates according to head-
ing.
North-up: North is at the top of the screen. When your heading changes, the ship icon
moves according to heading. This mode is for long-range navigation.
Course-up: The chart picture is stabilized, and shown with your current course (over

a new course, the picture resets to display the new course at the top of the screen. If
no destination is set, the course is upward on the screen at the moment course-up is
selected.
