Solution

1. Preparation

Gather necessary tools: socket set, multimeter, OBD-II scanner.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box, typically found near the driver's side dashboard or under the hood.
Identify the fuse responsible for the radio (refer to the owner's manual for the exact location).
Remove the fuse using a fuse puller or pliers and inspect it. If blown, replace it with a fuse of the same amperage.

3. Inspect Wiring and Connections

Remove the radio unit from the dashboard using a trim removal tool.
Carefully disconnect the wiring harness from the back of the radio.
Check for any damaged wires or loose connections. Repair or replace any faulty wiring as needed.

4. Test Power Supply

With the wiring harness disconnected, use a multimeter to check for voltage at the radio's power connector.
If there is no power, trace the wiring back to the fuse box and ignition switch to determine where the power loss occurs.

5. Inspect the Antenna

Check the connection of the antenna at the rear of the vehicle and make sure it's securely attached.
Inspect the antenna for any visible damage. If damaged, replace the antenna.

6. Reinstall and Test

Reconnect the wiring harness to the radio and carefully reinstall the unit back into the dashboard.
Reconnect the negative terminal of the battery.
Test the radio to see if functionality is restored.
