Compressed Audio Files (MP3/
WMA/AAC/ATRAC3)
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.

Compressed Video Files
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:

Your vehicle is equipped with Bluetooth®
Streaming Audio. If you have a compatible
Bluetooth®device with streaming audio (A2DP
profile) , you can set up the wireless connection
between your Bluetooth
®device and the in-
vehicle audio system. This connection allows
you to listen to the audio from the Bluetooth
®
device using your vehicle speakers. It also may
allow basic control of the device for playing and
skipping audio files using the AVRCP Blue-
tooth
®profile. All Bluetooth®Devices do not
have the same level of controls for AVRCP.
Please consult the manual for your Bluetooth
®
Device for more details.
Once your Bluetooth®device is connected to
the in-vehicle audio system, it will automatically
reconnect whenever the device is present in the
vehicle and you select Bluetooth
®Audio from
your audio system. You do not need to manually
reconnect for each usage.
