INSTALLING YOUR RADIO
Preparation for Installation
This radio may be installed in any 12-volt negative ground system vehicle.
Most current U.S. and Foreign vehicles use a negative ground system,
but some older models and some newer large trucks may have a positive
ground. Check the specifications for your vehicle before beginning
installation. Generally, you have a negative-ground system if the negative
(-) battery terminal is connected to the motor block. Contact your dealer if
you are unable to determine your vehicle’s polarity system.
1. Read these instructions completely before beginning installation.
2. Read and follow all safety precautions in your vehicle’s Service Manual.
3. Make sure all necessary tools, materials, and parts are on hand.
4. Disconnect the negative (-) battery cable before installing your radio. Be
sure to reconnect the cable when installation is complete.
5. Determine a mounting location for your radio. Choose a location that does
not impair visibility or interfere with driving. Also take into consideration
the routing and length of the lead wires and cables to the power source,
antenna, and/or optional external speaker.
CAUTION: Extreme care should be exercised when drilling into
the dash to avoid damage to under dash electronic ignition,
cruise control, instrument and/or accessory wiring.
