2. Remove the trim panel around the radio. There are usually four screws holding the trim panel in place. Use a Phillips head screwdriver to remove the screws, and then gently pry the trim panel off.
3. Disconnect the wiring harness from the back of the radio. There may be one or two harnesses that need to be disconnected. Use a flathead screwdriver to pry the harnesses apart, and then set the radio aside.
4. Remove the mounting brackets from the sides of the radio. There are usually two screws holding each bracket in place. Use a Phillips head screwdriver to remove the screws, and then pull the brackets off.
5. Pull the radio out of the dash. The radio should now be loose and able to be pulled out of the dash. Be careful not to damage any of the wiring or trim pieces as you remove the radio.
6. Install the new radio. Follow the steps in reverse order to install the new radio. Be sure to connect the wiring harness correctly, and tighten all of the screws securely.
7. Turn on the power to your car and test the radio. Make sure that the radio is working properly before you put the trim panel back on.
