3. When there are 2 map screens dis-
played to switch the “North
up”/“Heading up” of the right screen
map, select
“Right screen”
switch.
4. Select the “Map orient” of the
“Edit right screen”, and then the
“North up”/“Heading up” 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 of up to 300
feet can and should be expected. General-
ly, position errors will be corrected within
a few seconds.

replaced, the current vehicle position
mark may become incorrect.
To execute the fast distance tire calibra-
tion procedure, select the
