Heading
The Heading option allows you to set the display compass readings
to the following:
True
Auto Mag (automatic magnetic declination)
Manual Mag (manual magnetic declination)
WMM 2K (World Magnetic Model 2000)
Declination is the angle formed between magnetic north and true
north from the GPS receivers location.
True
The True selection uses true North as the compass heading.
Auto Mag
The Auto Mag selection displays all compass headings as magnetic
north using the magnetic declination value from the NMEA RMC
packet sent by the GPS satellite. The declination is applied to
the Auto Mag reading and appears on the GPS screen modifi ed,
adjusting for the altered declination degrees.
Note: If the receiver you are using is not able to use RMC or VTG
NMEA packets and the declination does not appear in the Diagnostic
screen, do not use Auto Mag with that receiver.
