Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical system.

2. Check and Replace the Radio Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and find the fuse associated with the radio.
Use a multimeter to check for continuity; if the fuse is blown, replace it with a new one of the same amperage.
Reinstall the fuse box cover.

3. Inspect Wiring and Connectors

Remove the radio from the dashboard by unscrewing any securing screws and gently pulling the unit out.
Inspect the wiring harness for any loose connections, frayed wires, or corrosion.
Reconnect any loose wires securely and repair any damaged wiring using electrical tape or butt connectors.

4. Test Radio Power Connection

With the multimeter, check the power connection to the radio harness for 12V when the ignition is turned on.
If there is no voltage, trace the wiring back to the source, looking for any open circuits or issues.

5. Reassemble and Test

Once repairs are made and connections verified, reinsert the radio into the dashboard.
Reconnect the battery.
Test the radio to ensure it powers on and functions correctly.
