Positioning the chart on the panel

Chart orientation

Several options are available for how the chart is rotated in the panel. The chart orientation

symbol in the panel’s upper right corner indicates the north direction.

North up Heading up Course up

North up

Displays the chart with the north direction upward. Corresponds to the usual orientation of

nautical charts.

Heading up

Displays the chart with the vessel’s heading directly up on the chart image. Heading

information is received from a compass. If heading is not available, then the COG from the

GPS will be used.

Course up

Rotates the chart in the direction of the next waypoint when in navigation mode. This option

works only when there’s an active route. If no route is active the heading up orientation will

be used until a route is made active.

Look ahead

This option centres the chart slightly forward of your vessel so that you can maximize your

view ahead.

Chart overlay

Radar, AIS and weather information can be displayed as overlay on your chart panel.

When radar or weather overlay is selected, the chart context menu will be expanded to

include basic function for the selected overlay.

Radar, weather and AIS functions are described in separate sections in this manual.

Using 3D charts

 Note: To use the 3D functionality you must have Navionics charts including 3D cartography

for the appropriate area.

For selecting cartography, see “Chart data” on page 19.

The boat icon

You can select diﬀ erent boat icons, and you can have extension lines as in traditional 2D

charting. Refer “3D boat selection” on page 20.

It is not possible to scale the boat icon to match actual boat size, and the size remains the

same independent on chart scaling.

Zooming 3D charts

You zoom the 3D chart by using the IN/OUT key. The rotary knob will not zoom 3D charts.
