SYSTEM DESCRIPTION
1. DISC PLAYER OUTLINE
(a) A CD player uses a laser pickup to read digital
signals recorded on CDs. By converting the digital
signals to analog, music and other content can be
played.
CAUTION:
Do not look directly at the laser pickup because
the CD player uses an invisible laser beam. Be
sure to operate the player only as instructed.
NOTICE:
• Do not disassemble any part of the CD player.
• Do not apply oil to the CD player.
• Do not insert anything but a CD into the CD
player.
(b) Usable discs
(1) The CD player can only play audio CDs, CD-Rs
(CD-Recordable), and CD-RWs (CD-
ReWritable) that have any of the following
marks:
(c) Precautions for use of discs
NOTICE:
• Copy-protected CDs cannot be played.
• CD-Rs and CD-RWs may not be played
depending on the recording conditions or
characteristics of the discs, or due to
damage, dirt, or deterioration caused by
leaving the discs in the cabin for a long time.
• Unfinalized CD-Rs and CD-RWs cannot be
played.
• Keep the discs away from dirt. Be careful not
to damage the discs or leave your
fingerprints on them.
• Hold discs by the outer edge and center hole
with the label side up.
• Leaving the disc exposed halfway out of the
slot for a long time after pressing the disc
eject button may cause deformation of the
disc, making the disc unusable.
• If discs have adhesive tape, stickers, CDR
labels, or any traces of such labels attached,
the discs may not be ejected or player
malfunctions may result.

• Keep the discs away from direct sunlight.
(Exposure to direct sunlight may cause
deformation of the disc, making the disc
unusable.)
• Do not use odd-shaped CDs because these
may cause player malfunctions.
• Do not use discs whose recording portion is
transparent or translucent because they may
not be inserted, ejected, or played normally.
HINT:
• When it is cold or it is raining, if the windows mist
up, mist and also dew may form in the player. In
such a case, the CD may skip or the CD may
stop in the middle of play. Ventilate or dehumidify
the cabin for a while before using the player.
• The CD may skip if the player experiences strong
vibrations when the vehicle is driven on rough
road or similar uneven surface(s).
(d) Cleaning
NOTICE:
Do not use a lens cleaner because it may cause
a malfunction in the pickup portion of the player.
(1) If dirt is on the disc surface, wipe it clean with a
soft dry cloth such as an eyeglass cleaner for
plastic lenses from the inside to the outside in a
radial direction.
NOTICE:
• Pressing on the disc by hand or rubbing
the disc with a hard cloth may scratch the
disc surface.
• Use of solvent such as a record spray,
antistatic agent, alcohol, benzine, and
thinner, or a chemical cloth may cause
damage to the disc, making the disc
unusable.

(c) ID3 tag and WMA tag
(1) Additional textual information called ID3 tag can
be input to MP3 files. Information such as song
titles and artist names can be stored.
HINT:
This player is compatible with the ID3 tags of ID3
Ver. 1.0 and 1.1, and ID3 Ver. 2.2 and 2.3.
(Number of characters complies with ID3 Ver.
1.0 and 1.1.)
(2) Additional textual information called WMA tag
can be input to WMA files. Information such as
song titles and artist names can be stored.
(d) Usable media
(1) Only CD-ROMs, CD-Rs (CD-Recordable), and
CD-RWs (CD-ReWritable) only can be used to
play MP3/WMA files.
NOTICE:
• CD-Rs and CD-RWs are more easily
affected by a hot and humid environment
than discs used for normal audio CDs. For
this reason, some CD-Rs and CD-RWs
may not be played.
• If there are fingerprints or scratches on
the disc, the disc may not be played or the
CD may skip.
• Some CD-Rs and CD-RWs deteriorate if
they are left in the cabin for a long time.
• Keep CD-Rs and CD-RWs in a storage
case that is impenetrable to light.
(e) Usable media format
(1) Usable media format
HINT:
• As for MP3/WMA files written in any format
other than those above, the contents of the
files may not be played normally or the file
names or folder names may not be displayed
correctly.
• This player is compatible with multi-session
discs and can play CD-Rs and CD-RWs on
which MP3/WMA files are added. However,
only the first session can be played.
• Discs whose first session includes both music
data and MP3 or WMA format data cannot be
played.
(2) Standard and restrictions

(f) File names
(1) Only files with an extension of ".mp3" or ".wma"
can be recognized and played as MP3 or WMA
files.
(2) Save MP3 or WMA files with an extension of
".mp3" or ".wma".
NOTICE:
If saving non-MP3 or non-WMA files with an
extension of ".mp3" or ".wma", those files
are wrongly recognized as MP3 or WMA files
and played. A loud noise may occur and
damage to the speaker may result.
3. AVC-LAN DESCRIPTION
(a) What is AVC-LAN?
AVC-LAN, an abbreviation for "Audio Visual
Communication Local Area Network", is a united
standard developed by the manufacturers in
affiliation with Toyota Motor Corporation. This
standard pertains to audio and visual signals as well
as switch and communication signals.
(b) Purpose:
Recently, car audio systems have rapidly developed
and the functions have vastly changed. The
conventional car audio system is being integrated
with multi-media interfaces similar to those in
navigation systems. At the same time, customers
are demanding higher quality from their audio
systems. This is merely an overview of the
standardization background. The specific purposes
are as follows:
(1) To solve sound problems, etc. caused by using
components of different manufacturers through
signal standardization.
(2) To allow each manufacturer to concentrate on
developing products they do best. From this,
reasonably priced products can be produced.
HINT:
• If a short to +B or short to ground is detected
in the AVC-LAN circuit, communication is
interrupted and the audio system will stop
functioning.
I100319E09

AV – 8AUDIO / VISUAL – AUDIO AND VISUAL SYSTEM
AV
• If an audio system is equipped with a
navigation system, the multi-display unit acts
as the master unit. If the navigation system is
not equipped, the audio head unit acts as the
master unit instead. If the radio and
navigation assembly is equipped, it is the
master unit.
• The radio receiver contains a resistor that is
necessary to enable communication on the
different AVC-LAN circuits.
• The car audio system with an AVC-LAN
circuit has a diagnostic function.
• Each component has a specified number (3-
digit) called a physical address. Each function
has a number (2-digit) called a logical
address.
4. COMMUNICATION SYSTEM OUTLINE
(a) Components of the audio system communicate with
each other via the AVC-LAN.
(b) The master component of the AVC-LAN is a radio
receiver with a 60 to 80
resistor. This is essential
for communication.
(c) If a short circuit or open circuit occurs in the AVC-
LAN circuit, communication is interrupted and the
audio system will stop functioning.
5. DIAGNOSTIC FUNCTION OUTLINE
(a) The audio system has a diagnostic function (the
result is indicated on the master unit).
(b) A 3-digit hexadecimal component code (physical
address) is allocated to each component on the
AVC-LAN. Using this code, the component in the
diagnostic function can be displayed.
