FREQUENTLY ASKED QUESTIONS
When do I need to calibrate the Wayfinder?
The Wayfinder needs to be calibrated when
used for the first time in a vehicle, when used
in a different location in the same vehicle,
when moved to a different vehicle or when the
battery was removed. The Wayfinder requires
re-calibration when the"DISTORTION"icon
displays in the upper left corner or when there
has been a change to your vehicle, such as the
installation of a new stereo.
What does it mean when the "DISTOR-
TION" icon displays in the upper left
corner?
"DISTORTION" indicates magnetic distor-
tion. Many things generate external magnetic
fields causing compass inaccuracy, including
metal and electronics. The Wayfinder senses
any significant change in magnetic fields."DIS-
TORTION" may display briefly when driving
over a bridge, under an overpass, over railroad
tracks, or within close proximity to something
with a strong magnetic field. Once the vehicle
has moved away from the source of interfer-
ence, the "DISTORTION" icon dissapears. If
the "DISTORTION" icon is continuously dis-
played in the upper left corner, it is usually a
sign that there has been a significant change in
magnetic fields, and calibration is necessary.
