mized. Similarly, the effect of weather con-
dition and cabin pressure changes must be
minimized in order for altitude readings to
be most accurate.
Will my weather forecast and barometric
pressure readings be accurate if my altitude
is changing?
The Wayfinder V7000 predicts the weather
based on changes in pressure. In addition
to changes in weather and cabin pressure,
pressure also varies depending on altitude.
A change of ±50ft (15m) in altitude can make
the weather forecast inaccurate. Therefore,
to obtain an accurate weather forecast when
you are changing altitude, make sure you
recalibrate the pressure sensor for that alti-
tude. When recalibrating for a new altitude,
weather forecasts may not be accurate for
24 hours. As a guideline, we recommend
using the altitude function while traveling
and the barometer and weather forecast func-
tion while the vehicle is stationary.
Why would my altimeter reading change
from one day to another when my vehicle is
parked at the same location?
Even slight weather changes can cause alti-
tude changes of up to 50 feet (15m), and
extreme weather can cause changes of up to
