●Cargo loaded on the roof luggage carrier, especially metal objects, may adversely
affect the reception of XM® Satellite Radio.
●Maintaining perfect radio reception at all times is difficult due to the continually
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 metallic objects to
the antenna wire mounted inside the rear quarter window.

●MP3 and WMA playback
• When a device containing MP3 or WMA files is connected, all files in the USBmemory 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 atleast 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.
