Step 1: Remove the old stereo
To remove the old stereo, you’ll need to first remove the trim panel that surrounds the stereo. This can usually be done with a trim tool or a flathead screwdriver.
Once the panel is removed, you’ll need to unscrew the stereo from the dash and unplug the wiring harness and antenna cable.

Step 3: Connect the antenna cable
The antenna cable connects the stereo to the car’s antenna. To connect the cable, simply plug it into the back of the stereo.
Step 4: Mount the new stereo
Mount the new stereo into the dash using the screws that came with the stereo. Make sure it’s secure and fits snugly.
Step 5: Test the system
Before you put everything back together, test the system to make sure everything is working properly. Turn on the stereo and make sure you can hear sound from all of the speakers.
