Heading
Select either degrees magnetic or degrees true for your heading data.
The units you set will be used to display all heading data, including
information received from other instruments on the system.
Magnetic Variation
The default setting for magnetic variation is Automatic, which means
that the variation value is taken from the data received via SeaTalk or
NMEA, with SeaTalk data given priority. If no variation data is received,
the variation value from the installed chart card is used.
If preferred, you can set a specific variation value. Use the trackpad to
change from Automatic to a value, and increase or decrease the value
in 0.1° steps. Press and hold the trackpad to change the value quickly.
