You can change the orientation of the
map from north–up to heading–up by
touching the orientation symbol at the
top left of the screen.
North–up symbol
Regardless of the direction of vehicle travel,
North is always up.
Heading–up symbol
The direction of the vehicle travel is always
up.
A red arrow indicates North.
This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc.
However, the accurate position
may not be shown depending on the sat-
ellite condition, road configuration, ve-
hicle condition or other circumstances.
The Global Positioning System (GPS) devel-
oped and operated by the U.S. Department
of Defense provides an accurate current ve-
hicle position using 3 to 4 satellites.
The
GPS system has a certain level of inaccura-
cy.
While the navigation system will com-
pensate for this most of the time, occasional
positioning errors up to 300 feet can and
should be expected.
Generally, position er-
rors will be corrected within a few seconds.
L00102
When your vehicle is receiving signals from
the satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle posi-
tion on the map display.
Tunnels, tall build-
ings, trucks, or even the placement of
objects on the instrument panel may obstruct
the GPS signals.
The installation of window tinting may also
obstruct the GPS signals.
Most window tint-
ing contains some metallic content that will
interfere with the GPS signal reception.
We
recommend not to use the window tinting on
vehicles equipped with navigation systems.
The GPS satellites may not send signals due
to repairs or improvements being made to
them.
