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 must be on and the compass/
temperature displayed. Press and hold the RESET button
for about 5 seconds until VAR 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. Press the RESET
button after selecting the proper zone to return to the
normal compass/temperature display.
NOTE: To ensure proper compass calibration, make
sure the compass variance is properly set before manu-
ally calibrating the compass (see variance map).
