1. Turn off the car and disconnect the battery. This will prevent any electrical accidents from happening while you're working.
2. Remove the trim panel around the radio. There are usually two or four screws that hold this panel in place.
3. Use the radio removal tools or bent coat hangers to release the radio from its mounting brackets. These tools are available at most auto parts stores. It may be necessary to gently pry the radio out of the dash with a flat-head screwdriver.
4. Disconnect the wiring harness from the back of the radio. Be careful not to damage the wiring harness.
5. Remove the radio from the car.
To install a new radio, simply reverse the steps above. Be sure to connect the wiring harness correctly, or you may damage the new radio.
