GPS is a position detecting system utilizing the signals
from GPS satellites deployed by the U.S. Department of
Defense. The Mobile Navigation System uses input from
three or more satellites and calculates the vehicle position
based on the principle of triangulation.
The positioning accuracy of the system corresponds to the
error display of the GPS which is from about 30 to 200 meters.
l If you are using the system for the first time, or if you have not used it for some time, it takes
about 5 minutes (or about 2 minutes in open areas) to calculate your vehicle’s position.
nGPS signal reception is poor in the following places
lThe GPS satellites are controlled by the U.S. Defense Department, which may intentionally
lower positioning accuracy. In such cases, there may be vehicle position deviations.
l There may be vehicle position deviations for some time until GPS signals are received after
turning on the ignition.
This function compares your vehicle’s tracking data with the road data on the map
disc, applies dead reckoning to determine the road you are driving on, and displays
your vehicle on that road on the map.
l Intelligent map matching addresses the following problems to achieve high accuracy in
vehicle positioning.
Position Correction for Elevated RoadsPosition accuracy is improved by detecting if the vehicle is
running on or under an elevated road.
Position Correction for Parking GaragesPosition accuracy is improved by detecting if the vehicle is
driving in an elevated or underground parking garage.
High-precision GyrosensorA gyro detects turns with an accuracy of 0.05° per second.
Combined with a speed sensor, it enables the system to
display the current vehicle position even where GPS signals
may be blocked.
l Using a spare tire in place of the regular one may cause vehicle position deviations.
l Any difference between the direction which your vehicle actually travels and that shown on
the map is automatically eliminated by azimuth correction.

If necessary
Although you may encounter the following problems in a route search, there is nothing
wrong with the system.
The navigation system is just a support system for the driver. The driver should always pay
attention to the traffic situation to safely make decisions. You may be unable to arrive at your
destination due to out-of-date information on a map disc. You should be especially careful
when selecting an urgent destination such as a hospital or a police station.

nRadio Reception
AM characteristics
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere. Therefore, they can reach
longer distances than FM signals. Because
of this, two stations may sometimes be
picked up on the same frequency at the
same time.
FM characteristics
An FM broadcast range is usually about 40–
50 km (25–30 miles) from the source.
Because of extra coding needed to break the
sound into two channels, stereo FM has
even less range than monaural (non-stereo)
FM. Signals from an FM transmitter are similar to
beams of light because they do not bend
around corners, but they do reflect.
Unlike AM signals, FM signals cannot travel
beyond the horizon. Therefore, FM stations
cannot be received at the great distances
possible with AM reception.
Atmospheric conditions can also affect FM
reception. High humidity will cause poor
reception. However, cloudy days may pro-
vide better reception than clear days.
Multipath noise
Since FM signals can be reflected by
obstructions, it is possible to receive both the
direct signal and the reflected signal at the
same time. This causes a slight delay in
reception and may be heard as a broken
sound or a distortion. This problem may also
be encountered when in close proximity to
the transmitter.

nOperating Tips for In-Dash CD
Changer
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or optical
components (prism and lens) in the In-dash
CD changer may become clouded with
condensation. At this time, the CD will eject
immediately when placed in the unit. A
clouded CD can be corrected simply by
wiping it with a soft cloth. Clouded optical
components will clear naturally in about an
hour. Wait for normal operation to return
before attempting to use the unit.
Handling the In-dash CD changer
The following precautions should be
observed.
l
Do not spill any liquid on the audio system.
l Do not insert any objects, other than CDs,
into the slot.
l The CD revolves at high speed within the
unit. Defective (cracked or badly bent) CDs
should never be used. l
Do not use non-conventional discs such as
heart-shaped, octagonal discs, etc. The
disc may not eject resulting in a
malfunction.
l If the memory portion of the CD is
transparent or translucent, do not use the
disc.
l A new CD may have rough edges on its
inner and outer perimeters. If a disc with
rough edges is used, proper setting will not
be possible and the In-dash CD changer
will not play the CD. In addition, the disc
may not eject resulting in a malfunction.
Remove the rough edges in advance by
using a ball-point pen or pencil as shown
below. To remove the rough edges, rub the
side of the pen or pencil against the inner
and outer perimeter of the CD.
l When driving over uneven surfaces,
the sound may jump.

nOperating tips for MP3
l
This audio system handles MP3 files that
have been recorded on CD-R/CDRW/CD-
ROMs. Discs that have been recorded
using the following formats can be played:
• ISO9660 level 1
• ISO 9660 level 2
• Joliet extended format
• Romeo extended format
l This unit handles MP3 files conforming to
the MP3 format containing both header
frames and data frames.
l If a disc has both music data (CD-DA) and
MP3 files, playback of the two file types
differs depending on how the disc was
recorded.
l Packet written discs cannot be played on
this unit.
l This unit does not play CDs recorded
using MP3i (MP3 interactive), MP3 PRO
and RIFF MP3 formats. Specialized glossary
MP3
Abbreviation for “MPEG Audio Layer 3”.
A technical standard for audio compression
as decided by an ISO (International
Organization for Standardization) MPEG
working group.
Use of MP3 allows for audio data to be
compressed to approximately a tenth of the
source data size.
ISO 9660
An international standard for logical
formatting of CD-ROM files and folders.
It is divided into three separate levels based
on differences in file naming procedures,
data configuration and other characteristics.
Bit rate
Refers to the volume of data per second,
expressed in bps (bits per second).
Generally, the larger the number of the
transfer bit rate when compressing an MP3
file, the more information regarding musical
reproduction it carries, and therefore the
better the sound quality.
Packet writing
A general term for the method, similar to that
used for floppy discs or hard drives, of
recording the required file in a single
increment on a CD-R and similar.

Rear View Monitor Cautions
The rear view monitor is a visual assist system when reversing the vehicle that provides
images from the rear of the vehicle.
Note
l
If water, snow, or mud is stuck on the camera lens, wipe it off using a soft cloth. If it cannot
be wiped off, use a mild detergent.
l If the camera temperature changes rapidly, such as by pouring hot water on it under cold
temperature conditions, the rear view monitor may not operate correctly.
Rear View Parking Camera Location
The rear view monitor is only a visual assist device when reversing the vehicle. The images on
the screen may be different from the actual conditions. Always drive carefully confirming the
safety of the rear and the surrounding conditions by looking directly with your eyes. Reversing the
vehicle by only looking at the screen may cause an accident or a collision with an object.
lWhen the display is cold, images may course across the monitor or the screen
and may be dimmer than usual, which could cause difficulty in confirming the
surrounding conditions of the vehicle. Always drive carefully confirming the safety
of the rear and the surrounding conditions by looking directly with your eyes.
l Do not apply excessive force to the camera. The camera position and angle
may deviate.
l Do not disassemble, modify, or remove it as it may no longer be waterproof.
l The camera cover is made of plastic. Do not apply degreasing agents,
organic solvents, wax, or glass coating agents to the camera cover. If any
are spilled on the cover, wipe off with a soft cloth immediately.
l Do not rub the cover excessively, or polish it using an abrasive compound or
