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
and UDF (2.01 or lower).
 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
discs.
 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 files.
 This system can play back AAC files
encoded by iTunes.

6. TIPS FOR OPERATING THE AUDIO SYSTEM
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.
 M3u playlists are not compatible with the
audio player.
 MP3i (MP3 interactive) and MP3PRO for-
mats are not compatible with the audio
player.
 The player is compatible with VBR (Vari-
able Bit Rate).
 When playing back files recorded as VBR
(Variable Bit Rate) files, the play time will
not be correctly displayed if the fast for-
ward or reverse operations are used.
 It is not possible to check folders that do
not include MP3/WMA/AAC files.
 MP3/WMA/AAC files in folders up to 8 lev-
els deep can be played. However, the
start of playback may be delayed when
using discs containing numerous levels of
folders. For this reason, we recommend
creating discs with no more than 2 levels
of folders. 
The play order of the compact disc with
the structure shown above is as follows:
 The order changes depending on the per-
sonal computer and MP3/WMA/AAC
encoding software you use.
001.mp3
002.wma
Folder 1
003.mp3Folder 2
004.mp3

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. 
Playlists created using “WINAMP” soft-
ware have a playlist file extension (.m3u).
 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-

2. SOME BASICS
The hands-free system enables calls
to be made and received without hav-
ing to take your hands off the steering
wheel.
This system supports Bluetooth
®.
Bluetooth® is a wireless data system
that enables cellular phones to be used
without being connected by a cable or
placed in a cradle.
The operating procedure of the phone
is explained here.
WA R N I N G
● While driving, do not use a cellular
phone or connect the Bluetooth® phone.
● Your audio unit is fitted with Bluetooth
®
antennas. People with implantable car-
diac pacemakers, cardiac resynchroni-
zation therapy-pacemakers or
implantable cardioverter defibrillators
should maintain a reasonable distance
between themselves and the Bluetooth
®
antennas. The radio waves may affect
the operation of such devices.
● Before using Bluetooth
® devices, users
of any electrical medical device other
than implantable cardiac pacemakers,
cardiac resynchronization therapy-pace-
makers or implantable cardioverter
defibrillators should consult the manu-
facturer of the device for information
about its operation under the influence
of radio waves. Radio waves could have
unexpected effects on the operation of
such medical devices.
NOTICE
● Do not leave your cellular phone in the
vehicle. The temperature inside may rise
to a level that could damage the phone.
INFORMATION
●If your cellular phone does not support
Bluetooth®, this system cannot function.
● In the following conditions, the system
may not function:
• The cellular phone is turned off.
• The current position is outside the
communication area.
• The cellular phone is not connected.
• The cellular phone has a low battery.
● When using Bluetooth
® audio and
hands-free at the same time, the follow-
ing problems may occur:
• The Bluetooth
® connection may be
cut.
• Noise may be heard on the Bluetooth
®
audio playback.
REGISTERING/CONNECTING
A Bluetooth® PHONE
To use the hands-free system for cellu-
lar phones, it is necessary to register a
cellular phone with the system.
