Speed Unit:
Select if you want the speed over ground to be displayed in mph (statute miles per hour), km/h (kilometers per hour) or
knots (nautical miles per hour).
UTC Offset:
Enter the UTC offset for your location. The UTC offset can be adjusted in half an hour increments.
Mag Var:
Select manual or automatic magnetic variation. Automatic variation is only possible if using an external NMEA compatible
GPS receiver.
Variation:
Enter the magnetic variation of your location. This is only used if you would like the instrument to display true heading.
True heading is the heading relative to the geographic North Pole. Magnetic heading is the heading relative to the mag-
netic North Pole. Variation is expressed in degrees east or west. Please note that should you move a long distance, you
may have to update the variation setting. This setting may be ignored if you only use the magnetic heading display option.
