10-16 Troubleshooting guide/General system information
AUDIO SYSTEM
Compact Disc (CD) player
Symptom Possible cause Possible solution
Music cannot be played back. The disc is inserted upside down. Insert a CD with the label side facing up.
Moisture condensation occurs inside the unit. Wait until the moisture evaporates. (approximately 1
hour)
The cabin temperature is too high. Wait until the cabin temperature becomes moderate.
The disc is scratched or dirty. A disc is not always
playable if it is scratched. Wipe off any dirt from the disc.
Depending on the condition in which they are stored,
discs may become unreadable due to deterioration (for
example, keeping the discs in the passenger compart-
ment, etc.). Change the disc with a deterioration-free disc. Do not
use a deteriorated disc. The label surface of the disc
may crack or chip, and the layer of the label surface may
eventually peel off.
The compressed audio files cannot be played back. If both music CD files (CD-DA data) and compressed
audio files (MP3 data, etc.) are mixed on one disc, the
audio compression files cannot be played back. Prepare a disc that includes compressed audio files
only.
The files are not named using characters that are
compliant with the specifications. Use the character codes and the number of characters
that are compliant with the specifications for folder
names and file names. In addition, always use ".MP3", ".
WMA", ".mp3" or ".wma" for file extensions.
It takes a long time before the music starts playing. The disc contains a large amount of data. Some time may be required to check the files. It is
recommended that unnecessary folders or any files
other than compressed audio files should not be
recorded in a disc.
Sound quality is poor. The disc is dirty. Wipe off any dirt from the disc.
No sounds are played though CD play time is displayed. The system plays back the first track of the mix mode
disc. (Mix mode is a format in which data except music
is recorded on the first track and music data is recorded
on other than the first track in a session.)
Play back music data that are recorded on other than
the first track.
