The Hyundai Sonata is a value packed car with lots of interior space and amenities for the money. Changing out the original stereo in the Hyundai Sonata requires removing a portion of the dash, which is easier than it sounds. With the right parts, this project takes less than an hour and leaves you with much improved sound.
Open the coin holder and remove the two screws at the front. Pry the trim from around the gearshift lever and unhook the power wire to the cigarette lighter.
Locate and remove the two screws from the bottom of the radio trim panel. Look for the screws, attached to a rod, below the glove box. Unhook the cable from the rod and pull the rod free.
Place the shifter into "D" and slide the radio trim panel away from the dash. Locate the four screws at the front and sides of the stereo and remove them.
Pull the stereo out of the Hyundai Sonata dash and disconnect the wires from the back of the unit. Connect the wiring harness adaptor to the original harness.
Slide the new head unit into the Hyundai radio adaptor kit. Attach the wiring harness adaptor and antenna wire to the back of the new head unit and push the entire assembly into the dash.
Secure the stereo in place with the four front and side screws and turn it on. Verify all of the speakers and features are working. Reattach the radio trim panel, insert the rod back into cable assembly and secure the trim around the gear shift.
