Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the radio fuse using the diagram on the fuse box cover or the owner's manual.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse; if it is blown (the wire inside is broken), replace it with a new fuse of the same amperage (usually 10A or 15A).
Reinstall the fuse and reconnect the negative battery terminal.

3. Inspect Wiring Harness

Remove the radio unit from the dashboard following the manufacturer’s guidelines.
Carefully disconnect the wiring harness from the back of the radio.
Inspect the connector for corrosion, bent pins, or broken wires.
If damaged, repair the wiring or replace the harness as necessary.
Reconnect the wiring harness securely.

4. Test the Radio

Reinstall the radio unit into the dashboard.
Reconnect the negative battery terminal.
Turn the ignition to the "On" or "Acc" position and check if the radio powers on.
