3. When there are 2 map screens dis-played to switch the “North
up”/“Headingup” of the right screen
map, select
“Right screen”
switch.
4. Select the “Map orient” of the
“Edit right screen”, and then the
“Northup”/“Headingup” of the right
screen is switched.
When 2 map screens are displayed, you
can set one as the “North −up” and the
other one as the “Heading −up.” This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, an accurate position
may not be shown depending on the
satellite condition, road configuration,
vehicle condition or other circum-
stances.
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate cur-
rent vehicle position using 3 to 4
satellites. The GPS system has a certain
level of inaccuracy built in for security
reasons. While the navigation system will
compensate for this most of the time, oc-
casional positioning errors up to 300 feet
can and should be expected. Generally,
position errors will be corrected within a
few seconds.

POSITION/DIRECTION CALIBRATION
1. Move the cursor mark to your
desired point by operating the select
and scroll lever of the navigation
controller.
Push the
“ENT” button on the naviga-
tion controller.
2. Operate the select and scroll lever of

The tire change calibration function
should be used when the tires are re-
placed. This will adjust for any possible
change in tire circumference from the
old tires to the new ones. If this proce-
dure is not performed when tires are
replaced, the current vehicle position
mark may become incorrect.
To execute the fast distance tire calibra-
tion procedure, select the
“Tire
change”
switch on the “Calibration”
screen.
The message appears and the fast dis-
tance calibration is automatically started.
A few seconds later, the map screen will
be displayed.
