Mounting

Please read entire manual before installation.

Before You Start

• Disconnect negative battery terminal. Consult a qualified technician for instructions.

• Avoid installing the unit where it would be subject to high temperatures, such as from
direct sunlight, or where it would be subject to dust, dirt or excessive vibration.

Getting Started

• Once a suitable location has been determined, drill the hole and secure the stereo
using the metal mounting bracket. If the bracket needs to be shortened, remove the
appropriate number of breakaway segments using a pair of pliers.

Mounting the Radio

1. Choose a mounting location on the dash board or instrument panel that will
allow room behind to run radio cables to the power source. Consider how you will use
the AUX IN, LINE OUT and USB connectors and route the appropriate extension cables
to an accessible area.

2. Cut a hole in the dash board using the template provided in the back of this manual. At
least 3 3/4” depth is needed to mount the radio.

IMPORTANT! Do not mount this unit where it can be submerged in water.

3. Slide the included spring washers (B) over the screw posts (A) and attach the screw
posts to the back of the radio.

4. Place the radio in front of the dashboard opening so the wiring can be brought through
the opening.

5. After completing the wiring connections, turn the radio on to confirm operation (vehicle
accessory switch must be on). If the radio does not operate, recheck all wiring until the
problem is corrected. Once proper operation is achieved, turn the accessory switch off
and proceed with final mounting of the radio. Refer to the “Wiring Diagram” on page 5.

NOTE: Before final installation, test the wiring connections to make sure the unit is con­nected properly and the system works.

6. Insert the radio into the mounting hole.

7. Place the “U” bracket (C) over the screw posts and secure the radio to the dash using
the included hex nuts (D). If necessary, cut the score marks (E) on either side of the
mounting bracket to custom fit the bracket length for your application. See Figure A.
