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
contents 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
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.

While driving
Do not connect or disconnect an iPod or USB memory or operate the con-
trols while driving. Doing so may lead to inattention to driving and cause a
serious accident.
