5.4 Chart setup
Navionics cartography comes pre-installed on your system. You
can also use Navionics chart cards: in that case, the system uses
whichever cartography is the latest.
To suit your particular requirements, you can configure how the
Chart application displays cartographic data.
There are three ways you can change chart settings:
• Chart Setup Menu.
• Cartography Setup Menu.
• Presentation softkey (see
page 63).
Changes are retained when you power off.
To open the Chart Setup Menu
1. Press the MENU key on the display unit.
2. Highlight Chart Setup.
3. Press the right-arrow on the trackpad.
Datum
The Chart application and your paper charts must use the same
datum to correlate accurately. The default datum for the display is
WGS1984. If that is not suitable, you can change it to one from the
set provided under the Datum option on the Chart Setup menu.
