UNIVERSAL INSTALLATION PROCEDURE USING MOUNTING SLEEVE
1. Remove the detachable front panel if it is attached to the chassis by pushing the “Release” button. Slide the mounting
sleeve off of the chassis. If it is locked into position, use the removal tools (supplied) to disengage it.
2. Check the dashboard opening size by sliding the mounting sleeve into it. If the opening is not large enough, carefully

cut or file as necessary until the sleeve easily slides into the opening. Do not force the sleeve into the opening or
cause it to bend or bow. Check that there will be sufficient space behind the dashboard for the radio chassis.
3. Locate the series of bend tabs along the top, bottom, and sides of the mounting sleeve. With the sleeve fully inserted
into the dashboard opening, bend as many of the tabs outward as necessary so that the sleeve is firmly secured to
the dashboard.
4. Place the radio in front of the dashboard opening so that the wiring can be brought through the mounting sleeve.
Follow the wiring diagram carefully and make certain all connections of the wiring harness are secure and insulated
with wire nuts or electrical tape to insure proper operation of the unit. After completing the wiring connections, attach
the front panel and turn the unit on to confirm operation (ignition switch must be “on”). If unit does not operate, recheck all wiring until problem is corrected. Once proper operation is achieved, turn off the ignition switch and proceed
with final mounting of the chassis.
5. Carefully slide the radio into the mounting sleeve making sure it is right-side-up until it is fully seated and the spring
clips lock it into place.
6. Attach one end of the perforated support strap (supplied) to the screw stud on the rear of the chassis using the hex
nut provided. Fasten the other end of the perforated strap to a secure part of the dashboard either above or below
the radio using the screw and hex nut provided. Bend the strap to position it as necessary.
CAUTION: The rear of the radio must be supported with the strap to prevent damage to the dashboard from the
weight of the radio or improper operation due to vibration.
7. Re-attach the front panel to the chassis and test radio operation by referring to the Operating Instructions for the unit.

ISO INSTALLATION PROCEDURE
This unit has threaded holes in the chassis side panels which may be used with the original factory mounting brackets
of some Toyota, Nissan, Mitsubishi, Isuzu, Hyundai and Honda vehicles to mount the radio to the dashboard. Please
consult with your local car stereo specialist shop for assistance on this type of installation.
1. Remove the existing factory radio from its dashboard or center console mounting. Save all hardware and brackets
as they will be used to mount the new radio.
2. Carefully un-snap the plastic frame from the front of the new radio chassis. Remove and discard the frame.
3. Remove the factory mounting brackets and hardware from the existing radio and attach them to the new radio.
CAUTION : DO NOT EXCEED M5 X 8 MM MAXIMUM SCREW SIZE.
LONGER SCREWS MAY TOUCH AND DAMAGE COMPONENTS INSIDE THE CHASSIS.
4. Wire the new radio to the vehicle as per step 4 above.
5. Mount the new radio assembly to the dashboard or center console using the reverse procedure of step 1.
