AUDIO AND VISUAL SYSTEM (w/o Navigation System) - SYSTEM DESCRIPTION

DISC PLAYER OUTLINE

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.

Usable discs

The CD player can only play audio CDs, CD-Rs (CD-Recordable) and CD-RWs (CD-ReWritable) that have any of the following marks:

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, CD-R 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 condensation may form in the player. In such cases, the CD sound may skip or stop in the middle of play. Ventilate or dehumidify the cabin for a while before using the player.
The CD sound may skip if the player experiences strong vibrations when the vehicle is driven on rough road or similar uneven surface(s).

Cleaning

  • NOTICE:
  • Do not use a lens cleaner because it may cause a malfunction in the pickup portion of the player.

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.

  • 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 do not play.
If there are fingerprints or scratches on a disc, the disc may not play or the CD sound may skip.
Some CD-Rs and CD-RWs may deteriorate if they are left in the cabin for a long time.
Keep CD-Rs and CD-RWs in an opaque case.

  • If non-MP3 or non-WMA files are saved with an extension of ".mp3" or ".wma", those files may be wrongly recognized as MP3 or WMA files and played. A loud noise may occur and damage to the speakers may result.
AVC-LAN DESCRIPTION

What is AVC-LAN?

Audio And Visual System (W/O Navigation System) - System Description. AUDIO / VIDEO. Land Cruiser URJ200 URJ202 GRJ200 VDJ200

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.


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:

To solve sound problems etc. caused by using components of different manufacturers through signal standardization.

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.
If the audio system has a navigation system installed, the multi-display unit acts as the master unit. If the navigation system is not installed, the audio head unit acts as the master unit instead. If the navigation receiver assembly is installed, it is the master unit.
The radio receiver assembly 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.
COMMUNICATION SYSTEM OUTLINE

Components of the audio system communicate with each other via the AVC-LAN.

The master component of the AVC-LAN is a radio receiver assembly with a 60 to 80 Ω resistor. This is essential for communication.

If a short circuit or open circuit occurs in the AVC-LAN circuit, communication is interrupted and the audio system will stop functioning.

DIAGNOSTIC FUNCTION OUTLINE

The audio system has a diagnostic function (the result is indicated on the master unit).

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.

"BLUETOOTH" OUTLINE

"Bluetooth" is a trademark owned by Bluetooth SIG. Inc.

"Bluetooth" is a wireless connection technology that uses the 2.4 GHz frequency band. This makes it possible to connect a cellular phone ("Bluetooth" compatible phone*1) to the radio receiver assembly (the "Bluetooth" system is built in), and use the handsfree function of the cellular phone, even if it is in a pocket or bag. As a result, it is not necessary to use a connector attached directly to the cellular phone.


*1: Some versions of "Bluetooth" compatible cellular phones may not function.

  • HINT:
  • The communication performance of "Bluetooth" may vary depending on obstructions or radio wave conditions between communication devices, electromagnetic radiation, communication device sensitivity or antenna capacity.

"Bluetooth" audio function

The "Bluetooth" built-in radio receiver assembly and a "Bluetooth" compatible portable audio player*2 can be connected using a "Bluetooth" wireless connection. This enables files stored in the portable audio player to be heard from the vehicle speakers. In addition, operations such as play/stop can be performed directly from the radio receiver assembly.


*2: Some versions of "Bluetooth" compatible audio players may not be able to operate the "Bluetooth" function, or music may play, but functions available using the radio receiver assembly may be limited.

Available "Bluetooth" audio devices

"Bluetooth" specifications Ver. 1.1, or higher (Recommended: Ver. 2.0 + EDR or higher)
Following Profiles
A2DP (Advanced Audio Distribution Profile) Ver. 1.0
AVRCP (Audio/Video Remote Control Profile) Ver. 1.0 or higher (Ver. 1.3 or higher recommended)

USB AUDIO SYSTEM FUNCTION OUTLINE

The No. 1 stereo jack adapter assembly is equipped with a USB terminal. Connecting a USB device or "iPod" to the No. 1 stereo jack adapter assembly allows music files to be played. Not only is it possible to play music from a USB device with audio functions, is also possible to play MP3 or WMA music files that are stored on a USB device. In addition, "iPod" control software is installed, allowing file selection from playlists and operation using shuffle mode.

  • HINT:
Visual contents of an "iPod" cannot be played.
Operation through the controls of a USB device or "iPod" cannot be performed while it is connected.

ASL (Automatic Sound Levelizer) FUNCTION OUTLINE

The Automatic Sound Levelizer (ASL) function automatically adjusts the sound data in order to enable to hear the clear sound from the audio system even when vehicle noise increases (as vehicle noise increases, the volume is turned up etc.). Vehicle speed signals are received from the combination meter assembly and used for the ASL.
