Chart orientation
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 to control how
your vessel and chart relate to one another and how they are
displayed on screen.
The mode you choose applies to the active chart instance, and
is restored at power up.
The following options are available:
North–Up
In North Up mode, the chart orientation is fixed with true north
upwards. As your heading changes the vessel symbol moves
accordingly. This is the default mode for the chart application.

Head-Up
Head Up mode displays the chart with your vessel's current
heading upwards. As the heading changes the vessel symbol
remains fixed and the chart picture rotates accordingly.
Note: To prevent continuous backwards and forwards
rotations as the vessel yaws from side-to-side, the chart will
not update unless the heading changes by at least 10 degrees
from the last displayed orientation.
Note: It is not possible to select Head Up when the motion
mode is set to True.
Course-Up
In Course Up mode, the chart picture is stabilized and shown
with your current course upwards. As your vessel'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
prioritizes 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.
If heading data becomes unavailable whilst in this mode, a
warning pop up message is displayed and the chart uses 0°
heading in relative motion.
Setting the chart orientation
From the chart application:
1. Select Menu.
2. Select Presentation.
3. Select Chart Orientation.
4. Select Head Up, North Up, or Course Up option, as
appropriate.
Once selected a tick will be placed next to the chosen
orientation and the screen will update to reflect the new
orientation.
Chart motion mode
The motion mode controls the relationship between the chart
and your vessel.
Whilst motion mode is active, as your vessel moves, the chart is
redrawn to keep the vessel on-screen. The 3 motion modes are:
• Relative Motion.
• True Motion.
• Auto Range.
