4. Select the “Map orient.” switch
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 up to 300 feet
can and should be expected. Generally,
position errors will be corrected within a
few seconds.

When your vehicle is not receiving signals
from the satellites, the “GPS” mark does
not appear at the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map display. Tunnels, tall
buildings, trucks, or even the placement of
objects on the instrument panel may ob-
struct the GPS signals.
The installation of window tinting may also
obstruct the GPS signals. Most window
tinting contains some metallic content that
will interfere with the GPS signal recep-
tion. We recommend not to use the win-
dow tinting on vehicles equipped with nav-
igation systems.
