Compact Disc (CD) with MP3 or WMA
(if so equipped)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 from CD-ROM can reduce the
file size by approximately 10:1 ratio (Sam-
pling: 44.1 kHz, Bit rate: 128 kbps) with
virtually no perceptible loss in quality. MP3
compression removes the redundant and
irrelevant parts of a sound signal that the
human ear doesn’t hear.
. 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.
. Bit rate — Bit rate denotes the number of
bits per second used by a digital music files.
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.

may malfunction due to humidity. If this
occurs, remove the USB device and dehu-
midify or ventilate the USB player comple-
tely.
. The USB player sometimes cannot function
when the passenger compartment tempera-
ture is extremely high. Decrease the tem-
perature before use.
. Do not leave USB memory in a place prone
to static electricity or where the air condi-
tioner blows directly. The data in the USB
memory may be damaged.
. The vehicle is not equipped with a USB
memory stick.

.Do not connect a USB device if a connector
or cable is wet. Allow the cable and/or
connectors to dry completely before con-
necting the USB device. If the connector is
exposed to fluids other than water, evapora-
tive residue may cause a short between the
connector pins.
. Large video podcast files cause slow
responses in an iPod
®. The vehicle center
display may momentarily black out, but it will
soon recover.
. If an iPod
®automatically selects large video
podcast files while in the shuffle mode, the
vehicle center display may momentarily
black out, but it will soon recover.
. Audiobooks may not play in the same order
as they appear on an iPod
®.
. An iPod nano
®(1st Generation) may remain
in fast forward or rewind mode if it is
connected during a seek operation. In this
case, please manually reset the iPod
®.
. An iPod nano
®(2nd Generation) will con-
tinue to fast forward or rewind if it is
disconnected during a seek operation.
. An incorrect song title may appear when the
Play Mode is changed while using the iPod

a higher quality of sound than MP3. .
