How do I set the orientation of the chart?

PRESENTATION...
The orientation of a chart refers to the relationship between the chart and the direction
that you are travelling in. It is used in conjunction with motion mode (see page
page 30
) to control how your boat and chart relate to one another and how they are
displayed on screen. The mode that you choose is restored at power up and consists of
the following:
Head Up (H-up)
Head Up mode displays the chart with your boat's current heading upwards. As the
heading changes the boat symbol remains fixed and the chart picture rotates accord-
ingly.

North Up (N-up)
In North Up mode, the chart orientation is fixed with true north upwards. As your
heading changes the boat symbol moves accordingly. This is the default mode for the
chart application.
Course Up (C-UP)
In Course Up mode, the chart picture is stabilized and shown with your current course
upwards. As your boat's heading changes, the ship symbol moves accordingly. If you
select a new course, the picture will reset to display the new course upwards.
The reference used for Course-Up depends upon the information available at a given
time. The system always prioritises this information in the following order.:
1. Bearing from origin to destination, i.e. intended course .
2. Locked heading from an Autopilot.
3. Bearing to waypoint.
4. Instantaneous heading.
CHART MODE AND
ORIENTATION...
To prevent continuous backwards and forwards rotations as the boat
yaws from side-to-side, the chart will not update unless the heading
changes by at least 10 degrees from the last displayed orientation.
It is not possible to select Head Up when the motion mode is set to True.
