(Variable Bit Rate (VBR) compatible)
MP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC
(Advanced Audio Coding) are audio com-
pression standards.
 This system can play MP3/WMA/AAC files
on CD-R, CD-RW discs and USB memory.
 This system can play disc recordings com-
patible with ISO 9660 level 1 and level 2
and with the Romeo and Joliet file system.
 When naming an MP3/WMA/AAC file, add
an appropriate file extension (.mp3/.wma/
.m4a).
 This system plays back files with .mp3/
.wma/.m4a file extensions as MP3/WMA/
AAC files respectively. To prevent noise
and playback errors, use the appropriate
file extension.
 This system can play only the first session
when using multi-session compatible CDs.
 MP3 files are compatible with the ID3 Tag
Ver. 1.0, Ver. 1.1, Ver. 2.2 and Ver. 2.3 for-
mats. This system cannot display disc
title, track title and artist name in other for-
mats.
 WMA/AAC files can contain a WMA/AAC
tag that is used in the same way as an ID3
tag. WMA/AAC tags carry information
such as track title and artist name.
 The emphasis function is available only
when playing MP3/WMA files recorded at
32, 44.1 and 48 kHz.
 This system can play back AAC files
encoded by iTunes.
 The sound quality of MP3/WMA files gen-
erally improves with higher bit rates. In
order to achieve a reasonable level of
sound quality, discs recorded with a bit
rate of at least 128 kbps are recom-
mended.

This is a general term that describes the
process of writing data on-demand to CD-
R, etc., in the same way that data is writ-
ten to floppy or hard discs.
 This is a method of embedding track-
related information in an MP3 file. This
embedded information can include the
track number, track title, the artist’s name,
the album title, the music genre, the year
of production, comments, cover art and
other data. The contents can be freely
edited using software with ID3 tag editing
functions. Although the tags are restricted
to a number of characters, the information
can be viewed when the track is played
back.
 WMA files can contain a WMA tag that is
used in the same way as an ID3 tag. WMA
tags carry information such as track title
and artist name. 
This is the international standard for the
formatting of CD-ROM folders and files.
For the ISO 9660 format, there are 2 lev-
els of regulations.
 Level 1: The file name is in 8.3 format (8
character file names, with a 3 character
file extension. File names must be com-
posed of one-byte capital letters and num-
bers. The “_” symbol may also be
included.)
 Level 2: The file name can have up to 31
characters (including the separation mark
“.” and file extension). Each folder must
contain fewer than 8 hierarchies.
 MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to
about 1/10 the size of that on conventional
discs.
 WMA (Windows Media Audio) is an audio
compression format developed by
Microsoft
®. It compresses files into a size
smaller than that of MP3 files. The decod-
ing formats for WMA files are Ver. 7, 8 and
9.

and refers to an audio compression tech-
nology standard used with MPEG2 and
MPEG4.

1Press the talk switch.
2Select “OK”.
3Say the tab selection command or se-
lect the desired tab.
Commands related with each function are
displayed on the screen of the each func-
tion tab. Some commonly used com-
mands are displayed on the screen of the
function tab.
INFORMATION
● The voice command system can be
operated while guidance is being spo-
ken, when “Voice Prompt Interrupt”
(→ P.64) is set to on. (It is not necessary
to wait for the confirmation beep before
speaking a command.)
● Voice commands may not be recognized
if:
• Spoken too quickly.
• Spoken at a low or high volume.
• The roof or windows are open.
• Passengers are talking while voice
commands are spoken.
• The air conditioning speed is set high.
• The air conditioning vents are turned towards the microphone.
● In the following conditions, the system
may not recognize the command prop-
erly and using voice commands may not
be possible:
• The command is incorrect or unclear.
Note that certain words, accents or
speech patterns may be difficult for the
system to recognize.
• There is excessive background noise, such as wind noise.
● The ability to dial a contact using voice
commands may take some time after the
power switch is in ACCESSORY or ON
mode, especially when the phone has
many contacts.
VOICE COMMAND SYSTEM

INFORMATION
● The other party’s voice will be heard
from the front speakers. The audio sys-
tem will be muted during phone calls or
when hands-free voice commands are
used.
● Talk alternately with the other party on
the phone. If both parties speak at the
same time, the other party may not hear
what has been said. (This is not a mal-
function.)
● Keep call volume down. Otherwise, the
other party’s voice may be audible out-
side the vehicle and voice echo may
increase. When talking on the phone,
speak clearly towards the microphone.
● The other party may not hear you clearly
when:
• Driving on an unpaved road. (Making
excessive traffic noise.)
• Driving at high speeds.
• The roof or windows are open.
• The air conditioning vents are pointed towards the microphone.
• The sound of the air conditioning fan is loud.
• There is a negative effect on sound quality due to the phone and/or net-
work being used.

NAVIGATION SYSTEM

6. TIPS FOR THE NAVIGATION SYSTEM
1. GPS (GLOBAL POSITIONING SYSTEM)
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate
current position, normally using 4 or more
satellites, and in some case 3 satellites.
The GPS system has a certain level of in-
accuracy. While the navigation system
compensates for this mo st of the time, oc-
casional positioning errors of up to 300 ft.
(100 m) can and should be expected. Gen-
erally, position errors will be corrected
within a few seconds. When the vehicle is receiving signals from
satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle po-
sition on the map screen. Tunnels, tall
buildings, trucks, or even the placement of
objects on the control panel may obstruct
the GPS signals.
The GPS satellites may not send signals
due to repairs or improvements being
made to them.
Even when the navigation system is re-
ceiving clear GPS signals, the vehicle po-
sition may not be shown accurately or
inappropriate route guidance may occur in
some cases.
LIMITATIONS OF THE
NAVIGATION SYSTEM
This navigation system calculates the
current position using satellite signals,
various vehicle signals, map data, etc.
However, an accurate position may not
be shown depending on satellite condi-
tions, road configuration, vehicle con-
dition or other circumstances.
NOTICE
●
The installation of window tinting may
obstruct the GPS signals. Most window
tinting contains some metallic content
that will interfere with GPS signal recep-
tion of the antenna in the instrument
panel. We advise against the use of win-
dow tinting on vehicles equipped with
navigation systems.
