Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. The mirror is
set to zone eight upon leaving the factory. It will be
necessary to adjust the compass to compensate
for compass variance if you live outside zone eight.
Under certain circumstances, such as during a long
distance cross-country trip, it will be necessary to adjust
for compass variance. If not adjusted to account for
compass variance, your compass could give false
readings.
To adjust for compass variance:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold the on/off button until the zone
number is displayed. The number shown is the
current zone number.
3. Scroll through the zone numbers that appear in the
window on the mirror by pressing the on/off button.
Once you find your zone number, release the
button. After about four seconds, the mirror will return
to the compass display, and the new zone number
will be set. If C or CAL appears in the compass
window, the compass may need calibration.
