vessel, as determined by the GPS receiver (the chart's
orientation changes when your course direction changes)

Once you set the desired chart orientation, the orientation
angle is automatically adjusted as needed, according to the
currently viewed chart, course, or trip leg.
Whenever the cursor is active on a chart (when you've pressed the

change. This doesn't mean the chart-orientation feature isn't
working. It is only temporarily inhibited, so that precision positioning
is retained with the
orientation, press the
CHART
screen.
When you rotate a chart by changing its orientation, the
following items also rotate:
• original paper-chart information, such as labels of
geographic features and depth readings
• the directional arrow markers of any displayed route or
trip, so that they correspond to the new orientation
• arrows for the current stations, marking the direction of
the current (but not the display of speed of the current),
so that they correspond to the new orientation
The waypoint symbols, waypoint names, and route names are
shown right-side up and are not rotated. Only the CHART
screen is turned by the chart-orientation setting; none of the
other screens are affected. Regardless of the chart-orientation
setting, the plotter grid is always displayed in the north-up
direction.
