HD Radio™ Technology troubleshooting guide
■
Reception sensitivity ●
Maintaining perfect radio recept ion 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. Experience Cause Action
Mismatch of time align-
ment- a user may hear a

MP3, WMA and AAC playback
• When a device containing MP3, WMA or AA C files is connected, all files in the
USB memory device are checked. Once th e file check is finished, the first MP3,
WMA or AAC file is played. To make the file check finish more quickly, we recom-
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
folder. If the same device is removed an d reconnected (and the contents have not
been changed), the USB memory device w ill resume play from the same point in
which it was last used. ●
Extensions
If the file extensions .mp3, .wma and .m4a are used for files other than MP3, WMA
and AAC 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 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.
