FREQUENTLY ASKED QUESTIONS
What does it mean when the degree symbol
on line 2 is flashing slowly?
This indicates magnetic distortion. Many
things generate external magnetic fields caus-
ing compass inaccuracy, including metal and
electronics. The Wayfinder V7000 senses any
significant change in magnetic fields and the
associated magnetic distortion that occurs.
The degree symbol may flash briefly when
driving over a bridge, under an overpass, over
railroad tracks, within close proximity to a
strong magnetic field, or when the battery is
installed. Once the vehicle has moved away
from the source of the magnetic field or has
been calibrated, the Wayfinder V7000 will be
accurate. If the degree symbol flashes contin-
uously or immediately after calibration, the
unit needs to be calibrated again, where there
is less magnetic interference.
How can I maximize weather forecast and
altitude accuracy?
The Wayfinder V7000 sensor cannot deter-
mine the specific cause of a pressure change,
such as if the change is due to weather con-
ditions, altitude changes, or cabin pressure.
Therefore, for barometer and weather fore-
cast readings to be most accurate, the effect
of altitude and cabin pressure must be mini-
