INSTALLATION
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
¾” 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. Re
fer 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.
