Compass
The compass displays the direction the
vehicle is traveling. The display 3 will
show you N, NE, E, SE, S, SW, W or NW.
i
The presence of buildings, bridges,
power lines and large antenna masts
can influence the displayed values. Me-
tallic or magnetic objects in or on the
vehicle can influence the accuracy of
the compass.
To make sure the display is correct, the
compass must be set to the proper geo-
graphic zone ( page 191). It may also be
necessary to calibrate the compass
( page 191).
