Important Notes
Before final installation, test the wiring connections to make sure the unit is connected properly and the system works.
Use only the parts included with the unit to ensure proper installation. The use of unauthorized parts can cause malfunctions.
Consult with your nearest dealer if installation requires the drilling of holes or other modifications to your vehicle.
Install the unit where it does not interfere with driving and cannot injure passengers if there is a sudden or emergency stop.
If the installation angle exceeds 30º from horizontal, the unit might not give optimum performance.
This unit is not waterproof and is intended for interior mounting applications only.
Exterior mounting of the unit requires use of an ASA approved marine housing.
Avoid installing the unit where it will be subject to high temperatures from direct sunlight, hot air, or from a heater, or where it would be subject to excessive dust, dirt or vibration.
DIN Front/Rear Mount
This unit can be property installed with either a “Front” (conventional DIN front mount) or “Rear”
(DIN rear mount installation, utilizing threaded screw holes at the sides of the unit chassis) mount. For details, refer to installation methods A and B.
DIN Front Mount (Method A)
1.
Slide the mounting sleeve off of the chassis if it has not already been removed. If it is locked into position, use the removal keys (supplied) to disengage it. The removal keys are depicted in “Removing the Unit” on page 3.
2.
Check the dashboard opening size by sliding the mounting sleeve into it. If the

Bend Tabs
Screw Stud 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 to firmly secure the sleeve to the dashboard.
4.
Place the radio in front of the dashboard opening so the wiring can be brought through the mounting sleeve.
5.
Follow the wiring diagram carefully and make certain all connections are secure and insulated with crimp connectors or electrical tape to ensure proper operation.
6.
After completing the wiring connections, turn the unit on to confirm operation (vehicle ignition switch must be on). If the unit does not operate, recheck all wiring until the problem is corrected. Once proper operation is achieved, turn the ignition switch off and proceed with final mounting of the chassis.
7.
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.
8.
Attach one end of the perforated support strap (supplied) to the screw stud on the rear of the chassis using the hex nut and spring washer 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 plain washer provided. Bend the strap, as necessary, to position it.

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.
9.
Test radio operation by referring to the operating instructions for the unit.
Removing the Unit
To remove the radio after installation:
1.
Insert fingers into the groove in the front of frame and pull out to remove the frame.
(When re-attaching the frame, point the side with a groove downwards and reattach.)
2.
Insert the removal keys straight back until they click, and then pull the radio out. If removal keys are inserted at an angle, they will not lock properly to release the unit.
Trim Plate Installation
Push the trim plate against the chassis until it is fitted.

DIN Rear Mount (Method B)
This unit has threaded holes in the chassis side panels which may be used with the original factory mounting brackets of some vehicles to mount the radio to the dashboard. Please consult with your local mobile stereo shop for assistance on this type of installation.
1.
Remove the existing factory radio from the dashboard or center console mounting. Save all hardware and brackets as they will be used to mount the new radio.
2.
Carefully unsnap the plastic trim ring from the front of the new radio chassis. Remove and discard the trim ring.
3.
Remove the factory mounting brackets and hardware from the existing radio and attach them to the new radio. Select a position where the screw holes of the bracket and the screw holes of the main unit are aligned (are fitted).
Tighten the screws at 2 places on each side. Do not exceed M5 x 9 MM maximum screw size. Longer screws
