200 feet (60m). Use the Alt.set feature as
often as possible and no less than once a
day to recalibrate altitude and reset baromet-
ric readings to sea-level pressure adjusted for
your altitude.
What is vehicle cabin pressure?
Changes in vehicle cabin pressure, caused by
opening or closing doors or windows or turn-
ing ventilation fans on or off, alters the baro-
metric pressure. A change of up to ±50 feet
(15m) in altitude can occur from cabin pres-
sure changes. To get a more accurate reading,
it is recommended that you close your win-
dows when traveling at highway speeds and
set your ventilation system to recirculate
inside air instead of bringing in outside air if
the fan is on. Pressing every morning
will reset the altimeter to its original setting.
How can the bearing point feature help me?
Following the position of the sun and spot-
ting familiar landmarks can give you an idea
of what direction you are heading in during
the day. This differs at night or on a foggy day
when the sun and landmarks are obscured.
By setting a bearing point and monitoring
your headings, you can be far more certain of
direction, even on unfamiliar roads.
