Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked safely and on a flat surface.
Disconnect the vehicle’s battery to avoid electrical shock.

2. Inspect Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuses related to the audio system (refer to the owner’s manual for the correct fuse locations).
Remove the fuses and visually inspect for any damage or burn marks.
Replace any blown fuses with new ones of the same amperage.

3. Inspect Wiring Connections

Access the back of the radio unit by removing the trim panel (use a trim removal tool to avoid damage).
Check all wiring connections for tightness and signs of wear or corrosion.
Reconnect any loose wires securely and ensure there are no visible damages.

4. Reset Audio System

Reconnect the vehicle's battery.
Follow the manufacturer's instructions to perform a soft reset of the infotainment system (usually involves holding down specific buttons on the touchscreen).
Test the radio function after the reset.

5. Replace Radio Unit (if needed)

If the radio still does not work, consider replacing the unit.
Disconnect the existing radio by removing the mounting screws and unplugging the wiring harness.
Install the new radio by reversing the disassembly steps, ensuring all connections are secure.
