This manual explains the operation of
the system. Please read this manual
carefully to ensure proper use. Keep
this manual in your vehicle at all times.
The screen shots in this document and
the actual screens of the system differ
depending on whether the functions
and/or a contract existed and the map
data available at the time of producing
this document.
In some situations when changing
between screens, it may take longer
than normal for the screen to change,
the screen may be blank momentarily
or noise may be displayed.
Please be aware that the content of this
manual may be different from the sys-
tem in some cases, such as when the
system’s software is updated.
The navigation system is one of the
most technologically advanced vehi-
cle accessories ever developed. The
system receives satellite signals from
the Global Positioning System (GPS)
operated by the U.S. Department of
Defense. Using these signals and other
vehicle sensors, the system indicates
your present position and assists in
locating a desired destination.
The navigation system is designed to
select efficient routes from your pres-
ent starting location to your destina-
tion. The system is also designed to
direct you to a destination that is unfa-
miliar to you in an efficient manner.
Map database is made based on
Harman International maps, whose
information source comes from HERE
maps. The calculated routes may not
be the shortest nor the least traffic con-
gested. Your own personal local knowl-
edge or “short cut” may at times be
faster than the calculated routes.
The navigation system’s database
includes Point of Interest categories to
allow you to easily select destinations
such as restaurants and hotels. If a des-
tination is not in the database, you can
enter the street address or a major
intersection close to it and the system
will guide you there.
The system will provide both a visual
map and audio instructions. The audio
instructions will announce the distance
remaining and the direction to turn
when approaching an intersection.
These voice instructions will help you
keep your eyes on the road and are
timed to provide enough time to allow
you to maneuver, change lanes or slow
down.
Please be aware that all current vehicle
navigation systems have certain limita-
tions that may affect their ability to per-
form properly. The accuracy of the
vehicle’s position depends on satellite
conditions, road configuration, vehicle
condition or other circumstances. For

3-6.Tips for the navigation s ystem
The Global Positioning System (GPS)
developed and operated by the U.S.
Department of Defense provides an
accurate current vehicle position, nor-
mally using 4 or more satellites, and in
some case 3 satellites. The GPS sys-
tem has a certain level of inaccuracy.
While the navigation system will com-
pensate for this most of the time, occa-
sional positioning errors of up to 100 m
(100 yards) can and should be
expected. Generally, position errors
will be corrected within a few seconds.
The GPS signal may be physically
obstructed, leading to inaccurate vehi-
cle position on the map display. Tun-
nels, tall buildings, trucks, or even the
placement of objects on the instrument
panel may obstruct the GPS signals.
The GPS satellites may not send sig-
nals due to repairs or improvements
being made to them.
Even when the navigation system is
receiving clear GPS signals, the vehi-
cle position may not be shown accu-
rately or inappropriate route guidance
may occur in some cases.
 Accurate current vehicle position
may not be shown in the following
cases:
• When driving on a small angled Y-
shaped road.
• When driving on a winding road.
• When driving on a slippery road such as
in sand, gravel, snow, etc.
• When driving on a long straight road.
• When motorway and surface streets run
in parallel.
• After moving by ferry or vehicle carrier.
• When a long route is searched during
high speed driving.
• After repeating a change of direction by
going forward and backward, or turning
on a turntable in the parking lot.
• When leaving a covered parking lot or
parking garage.
• When a roof carrier is installed.
• When driving with tire chains installed.
• When the tires are worn.
• After replacing a tire or tires.
GPS (Global Positioning
System)
This navigation system calculates
the current vehicle position using
satellite signals, various vehicle sig-
nals, map data, etc. However, an
accurate position may not be shown
depending on satellite condition,
road configuration, vehicle condi-
tion or other circumstances.
Limitations of the navigation sys-
tem
NOTICE
●The installation of window tinting may
obstruct the GPS signals. Most win- dow tinting contains some metallic content that will interfere with GPS
signal reception of the antenna. We advise against the use of window tint-ing on vehicles equipped with naviga-
tion systems.
