EON (Enhanced Other Network) system (for traffic announcement function)
If the RDS station (with EON data) you are listening to is not broadcasting a
traffic information program and the audio system is in the TA (Traffic
announcement) mode, the radio will be switched automatically to a station
broadcasting a traffic information program in the EON AF list when traffic
information begins.
When listening to a disc
When the traffic information program starts, the disc playback mode is inter-
rupted and the traffic information is automatically broadcasted. When the
program ends, the initial operation resumes.
When the battery is disconnected
All preset stations are erased.
Reception sensitivity
Maintaining perfect radio reception at all times is difficult due to the contin-
ually changing position of the antenna, differences in signal strength and
surrounding objects, such as trains, transmitters, etc.
The radio antenna is mounted inside the rear quarter window. To maintain
clear radio reception, do not attach metallic window tinting or other metal-
lic objects to the antenna wire mounted inside the rear quarter window.
About Time shift
The times at which playback is possible depend on the bit rate of the DAB
station to be recorded, the amount of DAB unit memory, and the time at
which reception of the broadcast began.

Title and chapter
Video and audio programs stored in DVD video discs are divided into parts
by title and chapter.
Title: The largest unit of the video and audio programs stored on DVD
video discs. Usually, one movie, one album, or one audio program is
assigned as a title.
Chapter: A title is comprised of one or more chapters.

MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1/10 of their original size by using
MP3 compression.
WMA (Windows Media Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 for-
mat.
There is a limit to the MP3 and WMA file standards that can be used and to
the media/formats on which the files are recorded.

Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit
rate of at least 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances,
depending on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3
and WMA files on the market, and depending on the status of the encod-
ing and the file format, poor sound quality or noise at the start of play-
back may result. In some cases, playback may not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may
take more time to recognize the disc and in some cases, playback may
not be possible at all.
• Microsoft, Windows, and Windows Media are the registered trademarks
of Microsoft Corporation in the U.S. and other countries.
CAUTION
DVD video precaution
Conversational speech on some DVDs is recorded at a low volume to
emphasize the impact of sound effects. If you adjust the volume assuming
that the conversations represent the maximum volume level that the DVD
will play, you may be startled by louder sound effects or startled when you
change to a different audio source.
Loud sounds may have a significant impact on the human body or pose a
driving hazard. Keep this in mind when you adjust the volume.

USB memory functions
When the USB memory is connected and the audio source is changed to
USB memory mode, the USB memory will start playing the first file in the
first folder. If the same device is removed and reinserted (and the contents
have not been changed), the USB memory will resume playing from the
same point it was last used.
Depending on the USB memory that is connected to the system, certain
functions may not be available. Disconnecting the device and reconnecting
it once again may resolve some malfunctions.
When using a USB memory
You may be unable to use the instrument panel power outlet if the USB mem-
ory is connected to the USB port at the same time.
Error messages for USB memory
“USB Error”: This indicates a problem in the USB memory or its connection.
“No music files found.”:This indicates that no MP3/WMA files are included
in the USB memory.
USB memory
Compatible devices
USB memory that can be used for MP3 and WMA playback.
Compatible device formats
The following device formats can be used:
• USB communication formats: USB2.0 HS (480 Mbps) and FS (12
Mbps)
• File formats: FAT16/32 (Windows)
• Correspondence class: Mass storage class
MP3 and WMA files written in any format other than those listed above
may not play correctly, and their file names and folder names may not be
displayed correctly.

• Maximum directory hierarchy: 8 levels
• Maximum number of folders in a device: 3000 (including the root)

with the extension .mp3 or .wma.
ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track
title, artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3, 2.4 ID3
tags.
(The number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the
track title and artist name in the same way as with ID3 tags.

MP3 and WMA playback
• When a device containing MP3 or WMA files is connected, all files in
the USB memory device are checked. Once the file check is finished, the
first MP3 or WMA file is played. To make the file check finish more
quickly, we recommend that you do not include any files other than MP3
or WMA files or create any unnecessary folders.
• When the USB device is connected and the audio source is changed to
USB memory mode, the USB device will start playing the first file in the
first folder. If the same device is removed and reinserted (and the con-
tents have not been changed), the USB device will resume play from the
same point in which it was last used.
Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and
WMA files, they will be skipped (not played).
Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit
rate of at least 128 kbps and a sampling frequency of 44.1 kHz.
• There is a wide variety of freeware and other encoding software for MP3
and WMA files on the market, and depending on the status of the encod-
ing and the file format, poor sound quality or noise at the start of play-
back may result. In some cases, playback may not be possible at all.

5465-4. Using the hands-free phone system (for cellular phone)
GS350/250_EE (OM30C36E)
When using the hands-free system
The audio system is muted when making a call.
If both parties speak at the same time, it may be difficult to hear.
If the incoming call volume is overly loud, an echo may be heard.
Try to face toward the microphone as much as possible when speaking.
In the following circumstances, it may be difficult to hear the other party:
• When driving on unpaved roads
• When driving at high speeds
• If a window is open
• If the air conditioning is blowing directly on the microphone
• If the air conditioning is set to high
• There is an effect from the network of the cellular phone
Conditions under which the system will not operate
If using a cellular phone that does not support Bluetooth®
If the cellular phone is turned off
If you are outside service range
If the cellular phone is not connected
If the cellular phone’s battery is low
When the cellular phone is not connected, “No connect” is displayed.

The antenna is built into the instrument panel. If the cellular phone is behind
the seat or in the console box, or touching or covered by metal objects, con-
nection status may deteriorate.
Battery charge/Signal status
This display may not correspond exactly with the cellular phone itself.
When the cellular phone is out of the service area or in a place inaccessible
by radio waves, “No service” is displayed.
When using Bluetooth® audio and hands-free system at the same time
The following problems may occur.
The Bluetooth® connection may be cut.
Noise may be heard on the Bluetooth® audio playback.
