BASIC OPERATIONS
RELATED TO AUDIO
• The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic
interference, etc.). Check the symptoms below to diagnose the malfunction.
• The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and oper-
ation of each piece of electrical equipment, and then determine the cause.
NOTE:
• CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incor-
rectly mastered by the customer on a computer.
• Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the ìred book Compact
Disc Standard and may not play.
Symptom
Possible cause
Possible solution
No image is displayed.
The brightness is at the lowest setting.
Adjust the brightness of the display.
The system in the video mode.
Push <DISC> to change the mode.
The display is turned off.
Push <Day/Night> to turn on the display.
The screen is too dim. The move-
ment is slow.
The temperature in the interior of the vehicle is low.
Wait until the interior of the vehicle has
warmed up.
Some pixels in the display are dark-
er or brighter than others.
This condition is an inherent characteristic of liquid
crystal displays.
This is not a malfunction.
Some menu items cannot be se-
lected.
Some menu items become unavailable while the ve-
hicle is driven.
Park the vehicle in a safe location, and
then operate the multi AV system.
Symptom
Cause and Counter measure
Cannot play
Check if the CD was inserted correctly.
Check if the CD is scratched or dirty.
Check if there is condensation inside the player, and if there is, wait until the condensation is gone
(about 1 hour) before using the player.
If there is a temperature increase error, the player will play correctly after it returns to the normal
temperature.
If there is a mixture of music CD files (CD-DA data) and MP3/WMA files on a CD, only the music
CD files (CD-DA data) will be played.
Files with extensions other than “.MP3”, “.WMA”, “.mp3”, or “.wma” cannot be played. In addition,
the character codes and number of characters for folder names and file names should be in com-
pliance with the specifications.
Check if the disc or the file is generated in an irregular format, This may occur depending on the
variation or the setting of MP3/WMA writing applications or other text editing applications.
Check if the finalization process, such as session close and disc close, is done for the disc.
Check if the CD is protected by copyright.
Poor sound quality
Check if the CD is scratched or dirty.
It takes a relatively long time before
the music starts playing.
If there are many folder or file levels on the MP3/WMA CD, or if it is a multisession disc, some
time may be required before the music starts playing.
Music cuts off or skips
The writing software and hardware combination might not match, or the writing speed, writing
depth, writing width might not match the specifications. Try using the slowest writing speed.
Skipping with high bit rate files
Skipping may occur with large quantities if data such as for high bit rate data.
