■HD Radio™ Technology troubleshooting guide
■Reception sensitivity
●Maintaining perfect radio reception at all times is difficult due to the continually chang-
ing position of the antenna, differences in si gnal strength and surrounding objects, such
as trains, transmitters, etc.
●The radio antenna is mounted inside the rear window. To maintain clear radio reception,
do not attach metallic window tinting or other metallic objects to the antenna wire
mounted inside the rear window.

●File names
The only files that can be recognized as MP3/WMA/AAC and played are those with
the extension .mp3, .wma or .m4a.
●Discs containing mult i-session recordings
As the audio system is compatible with multi session discs, it is possible to play discs
that contain MP3, WMA and AAC files. Howeve r, only the first session can be played.
●ID3, WMA and AAC 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 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.
AAC tags can be added to AAC files, making it possible to record the track title and
artist name in the same way as with ID3 tags.
●MP3, WMA and AAC playback
When a disc containing MP3, WMA or AAC fi les is inserted, all files on the disc are
first checked. Once the file check is fi nished, the first MP3, WMA or AAC file is
played. To make the file check finish more quickly, we recommend you do not write any
files to the disc other than MP3, WMA or AAC files or create any unnecessary fold-
ers.
Discs that contain a mixture of music data and MP3, WMA or AAC format data can-
not be played.
●Extensions
If the file extensions .mp3, .wma and .m4a are used for files other than MP3, WMA
and AAC files, they may be mistakenly recognized and played as MP3, WMA and
AAC files. This may result in large amount s of interference and damage to the speak-
ers.
●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 poss ible in some instances, depending on
the characteristics of the disc.
• There is a wide variety of freeware an d other encoding software for MP3, WMA
and AAC files on the market, and depending on the status of the encoding and the
file format, poor sound quality or noise at the start of playback may result. In some
cases, playback may not be possible at all.
• When files other than MP3, WMA or AAC 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.

mend that you do not include any files other than MP3, WMA or AAC files or cre-
ate any unnecessary folders.
• When a USB memory device is connected and the audio source is changed to USB memory mode, the USB memory device will st art playing the first file in the first

been changed), the USB memory device w ill resume play from the same point in
which it was last used.
