Inspect the wiring harness for any loose or damaged connections.
Ensure that the wiring is securely connected to both the radio and the vehicle’s electrical system.
Reassemble the radio and trim, reconnect the battery, and test the radio.

4. Test Antenna Connection

While the radio is removed, inspect the antenna connection at the rear of the radio unit.
Ensure the antenna cable is securely connected and not damaged.
Reattach any loose connections, reassemble the radio, and test the functionality.

5. Replace the Radio (if necessary)

If previous steps did not resolve the issue, consider replacing the radio unit.
