This unit is designed for installation in cars, trucks, and vans with an existing radio opening. In many cases, a
special installation kit will be required to mount the radio to the dashboard. These kits are available at electronics
supply stores and car stereo specialist shops. Always check the kit application before purchasing to make sure the kit
works with your vehicle. If you need a kit but cannot find it available, call our toll-free “HELP” line (1-800-645-4994).
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, re-check 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

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
