Compressed Audio Files (MP3/WMA/
AAC)
Explanation of terms:
.MP3 — MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is the
most well known compressed digital audio
file format. This format allows for near “CD
quality” sound, but at a fraction of the size of
normal audio files. MP3 conversion of an
audio track can reduce the file size by
approximately a 10:1 ratio (Sampling: 44.1
kHz, Bit rate: 128 kbps) with virtually no
perceptible loss in quality. The compression
reduces certain parts of sound that seem
inaudible to most people.
. WMA — Windows Media Audio (WMA) is a
compressed audio format created by Micro-
soft as an alternative to MP3. The WMA
codec offers greater file compression than
the MP3 codec, enabling storage of more
digital audio tracks in the same amount of
space when compared to MP3s at the same
level of quality.
. AAC/M4A — Advanced Audio Coding
(AAC) is a lossy audio compression format.
Audio files that have been encoded with
AAC are generally smaller in size and deliver
a higher quality of sound than MP3. .
Bit rate — Bit rate denotes the number of
bits per second used by a digital music file.
The size and quality of a compressed digital
audio file is determined by the bit rate used
when encoding the file.
. Sampling frequency — Sampling frequency
is the rate at which the samples of a signal
are converted from analog to digital (A/D
conversion) per second.
. Multisession — Multisession is one of the
methods for writing data to media. Writing
data once to the media is called a single
session, and writing more than once is
called a multisession.
. ID3/WMA Tag — The ID3/WMA tag is the
part of the encoded MP3 or WMA file that
contains information about the digital music
file such as song title, artist, album title,
encoding bit rate, track time duration, etc.
ID3 tag information is displayed on the
Album/Artist/Track title line on the display.

Playback order:
. The folder names of folders not containing
compressed audio files are not shown in the
display.
. If there is a file in the top level of a disc/USB,
“Root Folder” is displayed.
.The playback order is the order in which the
files were written by the writing software, so
the files might not play in the desired order.
. Music playback order of compressed audio
files is as illustrated.

Troubleshooting guide:
SymptomCause and Countermeasure
Cannot play Check if the disc or USB device was inserted correctly.
Check if the disc 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 compressed audio files on a CD, only the music CD files (CD-DA data) will
be played.
Files with extensions other than “.MP3 (.mp3)”, “.WMA (.wma)”, “.AAC (.aac)”, “.M4A (.m4a)”, or “.AA3 (.aa3)” cannot be played. In
addition, the character codes and number of characters for folder names and file names should be in compliance 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
compressed audio 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 disc or USB device is protected by copyright.
Poor sound quality Check if the disc 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 disc or USB device, 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, etc., might not
match the specifications. Try using the slowest writing speed.
Skipping with high bit rate files Skipping may occur with large quantities of data, such as for high bit rate data.
Move immediately to the next song
when playing. If an unsupported compressed audio file has been given a supported extension like .MP3, or when play is prohibited by copyright
protection, the player will skip to the next song.
The songs do not play back in the
desired order. The playback order is the order in which the files were written by the writing software, so the files might not play in the desired order.
Random/Shuffle may be active on the audio system or on a USB device.
Compressed Video Files (models with

Explanation of terms:
.DivX®- DivX®refers to the DivX®codec
owned by DivX, Inc. used for a lossy
compression of video based on MPEG-4.
. AVI - AVI stands for Audio Video Interleave.
It is a standard file format originated by
Microsoft Corporation. A “.divx” encoded file
can be saved into the “.avi” file format for
playback on this system if it meets the
requirements stated in the table in this
section. However, not all the “.avi” files are
playable on this system since different
encodings can be used than the DivX
®
codec.
. ASF - ASF stands for Advanced Systems
Format. It is a file format owned by Microsoft
Corporation. Note: Only “.asf” files that meet
the requirements stated in the table in this
section can be played.
. Bit rate — Bit rate denotes the number of
bits per second used by a digital video file.
The size and quality of a compressed digital
audio file is determined by the bit rate used
when encoding the file. Requirement for Supporting Video Playback:

Bluetooth®Audio player (models with
navigation system)
. Some Bluetooth®audio devices may not be
recognized by the in-vehicle audio system.
. It is necessary to set up the wireless
connection between a compatible Blue-
tooth
®audio device and the in-vehicle
Bluetooth®module before using the Blue- tooth
®audio player.
. Operating procedure of the Bluetooth®
audio player will vary depending on the
device. Make sure it is understood how to
operate an audio device before using it with
this system.
. The Bluetooth
®audio player may be
stopped under the following conditions:

4-42Center display, heater, air conditioner, audio, phone and voice recognition systems
— Receiving a hands-free call.
— Checking the connection to the hands-free phone.
. Do not place a Bluetooth
®audio device in
an area surrounded by metal or far away
from the in-vehicle Bluetooth
®module to
prevent tone quality degradation and wire-
less connection disruption.
. While an audio device is connected through
a Bluetooth
®wireless connection, the bat-
tery power of the device may discharge
quicker than usual.
. This system supports the Bluetooth
®Audio
Distribution Profile (A2DP, AVRCP).
. Wireles LAN (Wi-Fi) and the Bluetooth
®
functions share the same frequency band
(2.4 GHz) . Using the Bluetooth®and the
wireless LAN functions at the same time may
slow down or disconnect the communica-
tion and cause undesired noise. It is
recommended that you turn off the wireless
LAN (Wi-Fi) when using the Bluetooth
®
functions.
