• Use only the supplied mounting hardware for

a safe and secure installation.

If you have any questions or problems
concerning your unit that are not covered in
this manual, please consult your nearest Sony

Stick one piece of the Velcro tape provided to
the bottom of the unit and the other to the

3 Start playing the device selected in 2.

For the playback method of the selected device,
refer to its operating manual.

4 Adjust the volume of the master unit and

selected device.

Notes
• Follow the steps below to play the audio file of

the computer connected to the USB jack of this
unit.
1 Press the MODE button of the master

unit to select “USB.”

2 Open the playback software (Windows

Media Player, etc.) on your computer.

3 Play the audio file (MP3,etc.).
After playing the audio file on the computer, if
you select “USB“ mode on the display of the
master unit, this unit may not recognize the
signal and sound may not come out.

• As the volume settings of each connected

device may differ, adjust the volume on each
device separately. As the sound output differs
on AUX IN 1 and AUX IN 2, connect the Sony
car audio DVD changer to AUX IN 1, and
connect a portable device (such as MD
WALKMAN, etc.) to AUX IN 2.

• While playing audio file in a device connected

to AUX IN 1, AUX IN 2, or the USB jack on this
unit, do not change any settings of the CD
