Solution

1. Preparation

Gather tools: flathead screwdriver, Phillips screwdriver, multimeter, OBD-II scanner.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace the Radio Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the radio fuse using the fuse diagram on the fuse box cover.
Remove the fuse with a fuse puller or needle-nose pliers.
Inspect the fuse for any visible damage (broken filament or discoloration).
If blown, replace it with a new fuse of the same amperage rating (usually 10A or 15A).

3. Check Radio Connections

Reconnect the negative battery terminal temporarily to power the radio.
Use a flathead screwdriver or Phillips screwdriver to remove the radio unit from the dashboard.
Carefully disconnect the wiring harness from the back of the radio.
Inspect the wiring for any frays, corrosion, or loose connections.
Reconnect the harness securely and reassemble the radio unit.

4. Testing Power and Ground

With the radio unit removed, use a multimeter to check for power at the radio connector.
Set the multimeter to the DC voltage setting and measure between the power wire and ground. You should see battery voltage (around 12V).
If no voltage is present, trace the power wire back to the fuse box and check for continuity.
If there’s power but no ground, check the ground wire connection to the vehicle chassis.

5. Resetting the Radio

If no issues are found, perform a factory reset of the radio via the vehicle's settings:
- Turn on the ignition without starting the engine.
- Navigate to the audio settings on the display.
- Select 'Factory Reset' and confirm.
After resetting, test the radio function.
