COMPACT DISC (CD) PLAYER
SymptomPossible 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 (approxi- mately 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 compartment, 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 specifi-
cations 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.
The sound quality is poor. The disc is dirty.Wipe off any dirt from the disc.

SymptomPossible cause Possible solution
No sounds are played though the 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 one other than the
first track in a session.)Play back music data that is recorded on a track
other than the first track.
Music cuts off or skips. The combination of writing software and hard-
ware might not match; or the writing speed,
writing depth, writing width, etc. might not
match the specifications. Create a disc using different writing speed
settings, etc.
The system skips the selected track and moves
to the next track. A non-MP3/WMA file is given an extension of “.
MP3”, “.WMA”, “.mp3” or “.wma”.Prepare MP3/WMA files.
The system plays back a file that is prohibited
due to copyright protection. Prepare playable files.
The tracks do not play back in the desired order. The folder locations in the disc are changed by the writing software while the files are written
in the disc.Check the settings of the writing software, and
create a new disc.
The CD cannot be ejected. The ignition switch is not placed in the ACC or
ON position. Place the ignition switch in the ACC or ON
position.

this procedure above, reset the iPod®.
The iPod® that is to be connected is not
compatible with the system. Check the iPod® model and firmware versions
available for the system.
The connected USB extension cable is not
compatible with the system. Replace the USB extension cable if the system
still does not recognize the iPod® after recon-
necting the cable properly a number of times.
The cable is rapidly connected to or discon-
nected from the USB connection port. Slowly connect or disconnect the USB cable.
An iPod® cannot be operated. The iPod® is connected to the in-vehicle audio
system while headsets, etc. are connected to the

a call, the hands-free function becomes
unavailable. Some models of a cellular phone do not switch
to the hands-free mode when they are operated
to make a call. This is not a malfunction. Make another call using the
hands-free function.
The other party’s voice cannot be heard.
There is no ringtone. The volume level is set to the minimum. Adjust the volume level.

Each volume level (ringtone, incoming voice
or outgoing voice) is different. Each volume level is not adjusted properly. Adjust each volume level properly.
The antenna display and remaining battery
level are different between the touch
screen display and a cellular phone screen.
Making or receiving a call is unavailable
even though the antenna display shows
that it is possible to do so. The antenna display varies depending on the
model of cellular phone.
This does not indicate a malfunction. The antenna
display and remaining battery level shown on the
touch screen display may be different from those
shown on the cellular phone screen. Use them as a
reference.
A voice cannot be heard clearly when using
a cellular phone behind tall buildings. Some structures such as tall buildings, etc. may
cause irregular reflection of radio waves or
completely shut out radio waves that are used
for cellular phones. Move to a place without tall buildings.
Noise is heard when using a cellular phone
under/near areas of elevated railroads,
high voltage electric power cables, traffic
signals, neon billboards, etc. Electromagnetic waves that are generated from
radio devices may adversely affect the cellular
phone.
This is not a malfunction.
Noise is heard in the sound from the audio
system while using a cellular phone. Radio waves that are generated from a cellular
phone may adversely affect the sound from the
audio system. This is not a malfunction.
Sound skips or stutters. The cellular phone may have turned on the wireless LAN (Wi-Fi). Turn off the wireless LAN (Wi-Fi).
