9.13 Chart orientation

The orientation of a chart refers to the relationship
between the chart and the direction that you are
travelling in.
The mode you choose applies to all chart views, 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 pointing up (this is the usual
orientation for nautical charts). As your heading
changes the vessel symbol rotates accordingly. This
is the default orientation for the Chart application.
Course Up
In Course Up mode, during active navigation,
the Chart application displays the vessel's current
destination waypoint directly up. As your COG
changes, the boat symbol moves accordingly. If you
select a new course, the picture will reset to display
the new course upwards.
If COG data becomes unavailable Course Up mode
is suspended and the Chart application will set COG
to 0°.
Setting the chart orientation
From the chart application menu:
1. Select Chart settings.
