The Ford Focus was introduced as a 2000 model year entry into the compact market. With sleek styling and trim levels designed to turn the heads of young buyers, the Focus has successfully competed with the Japanese automakers who have traditionally lead this market. Changing out the stereo in the Focus requires more mechanical skill than most stereo swaps, especially for the 2008 model addressed here.
Unhook the neutral wire on the battery before starting. Set out a small baby food jar or plastic cup to help secure screws and bolts while working under the dash.
Pull the emergency brake up and set an automatic transmission in "Drive" without turning the car on. Open the middle compartment in the center console and pry the plastic up with a flathead screwdriver.
Remove the console and the screw on either side of the power terminals to loosen the radio housing. Use the flathead screwdriver to remove the dash piece located over the passenger airbag.
Locate and remove the two screws directly above the instrument panel. Place the steering wheel in the lowest possible setting so you can pull out the unfastened plastic piece.
Pry the air vents located over the radio assembly out of the Ford Focus dash. Remove the two screws holding the console and radio, and pull the entire center portion of the dash out by pulling down from the top.
Disconnect the wiring harness from the back of the unit and change out the original harness adapter for the new one. Connect the harness to the back of the stereo and slide the unit into the center console trim.
Connect the neutral cable on the battery and test the stereo to ensure all of the speakers are working. Screw the console back in place and reattach all of the trim and molding.
