Automatic Compass Calibration
The automatic calibrating feature of the compass elimi-
nates the need to calibrate the compass due to normal
varying conditions.
Compass Variance Selection
Variance is the difference between magnetic North and
geographic North. For proper compass function, the
correct variance zone must be set. Refer to the variance
map for the correct variance zone. To check the variance
zone, the ignition switch must be on and the compass/
temperature displayed. Press and hold the STEP button
for about 5 to 10 seconds until ZONE and the number
appears in the display. The number displayed is the
variance zone used by the compass. To change the zone,
press the STEP button to scroll through numbers 1
through 15.
When the correct variance is selected release the step
button and the Compass/Temperature display will re-
turn to normal after approximately 15 seconds.
