Introduction
Thank you for purchasing the Digital Link Sound System (XDP-MU110).
This system allows you to digitally integrate an iPod/iPhone into your existing car audio unit.
You can enjoy exciting sound from your car audio unit and iPod/iPhone via this system, which
features sound settings optimized for your vehicle type by using Sony’s original digital sound
technology.
The DSP master unit makes a natural “front sound field” possible, so that you can feel bass as
though it comes from directly in front of the driver’s seat even though the subwoofer is located
at the rear of your car, e.g., in a cargo area.
There is also a digital connection for an iPod/iPhone so that you can enjoy high quality sound
in your car without noise/distortion.
Enjoy the new sound experience with this Digital Link Sound System.
Getting Started
Resetting the unit
Before operating the system for the first time, or after replacing the car battery or changing
connections, you should reset the system (page 5).

Setting up the Cradle
Precautions
• Install the cradle on a dashboard properly so
that the unit will not interfere with normal
driving.
• Follow the instructions on this manual about
dealing with the suction cup to secure the
cradle on a dashboard. If you fail to do so,
the adhesive strength of the suction cup may
decrease, and the cradle may fall down.
• If the cradle becomes detached, a traffic
accident may result. To prevent this, use the
supplied strap.
• Keep the cradle out of the reach of children.
Should a small part of the cradle be
swallowed, immediately consult a doctor.
• Remove the cradle from the dashboard and
keep it out of direct sunlight after use.
Leaving it on a dashboard or in a car where it
will be exposed to high temperature may
cause malfunction, and it may also damage
the dashboard.
• An iPod/iPhone may not be charged if you
put it on the cradle when the temperature in
the car is extremely high/low.
• Be careful not to splash water on the cradle.
It may cause a malfunction.
• To disconnect the cradle cord, pull it out by
its connector, not the cord.
