AUDIO SYSTEM
HD RADIO TECHNOLOGY
Sound
Symptom Possible cause Possible solution
Delay in digital audio on HD Radio broadcasts. The radio acquires an analog station first and blends to an digital signal.This is not a malfunction.
Audio skip, stutter or echo. The radio station has not properly aligned the
digital and analog audio. Verify correct operation on another station.
Report any station with poor performance.
Volume changing up/down. The radio station has not properly aligned digital
and analog audio level. Verify correct operation on another station and
check www.hdradio.com for stations in the area.
Report any station with poor performance.
Sound fading in and out. The transition between analog and digital is
taking place (blending). Verify transition performance on several sta-
tions in the area. Report any stations with poor
alignment.
Excessive blending (Transition between analog
and digital). The vehicle is located near the edge of the digital
coverage area.Refer to hdradio.com to verify radio stations in
your coverage area.
Digital audio not better than analog audio. Audio processing on the digital audio at a station can potentially decrease the digital audio
sound quality.Verify correct operation on another station.

SymptomPossible cause Possible solution
Keep losing my local stations. The digital coverage is slightly less than the
analog signal coverage. Verify correct operation on another station. This
is expected behavior.
Shadowing (urban / terrain) can cause reduced
digital coverage. Verify correct operation on another station.
Some data fields are blank. Text information is sent at the broadcaster’s
discretion. Verify correct operation on another station.

Text information is truncated / appears to be
more available. The display is limited to a fixed number of
characters and more data is being sent than can
be shown.This is intended behavior. Refer to the Owners
Manual for ability to access addition.
AM reception changes at night AM stations are required by the government
(FCC) to lower their power at night. This is not a malfunction.

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 are recorded on one
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.

(less than 3,000 tracks).
The shuffle function is turned on. Turn off the shuffle function if many tracks are
stored on the iPod®.
Music cannot be played back. A connector is not connected to the iPod®. Firmly connect the connector until it clicks.
