Compass
When navigating, points to your destination, regardless of the
direction you are moving. When points toward the top of the
electronic compass, you are traveling directly toward your
destination. If points any other direction, turn until it points
toward the top of the compass.
Calibrating the Compass
Before you can calibrate the electronic compass, you must be
outdoors, away from objects that influence magnetic fields, such
as cars, buildings, or overhead power lines.
The device has a 3-axis electronic compass (GPSMAP 64s and
GPSMAP 64st models only). You should calibrate the compass
after moving long distances, experiencing temperature changes,
or changing the batteries.
