Solution

1. Preparation

Gather tools: socket set, flat-head screwdriver, trim removal tools, multimeter.
Disconnect the negative terminal of the battery to ensure safety while working on the electrical system.

2. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse for the radio and remove it using a fuse puller.
Inspect the fuse; if it is blown, replace it with a new fuse of the same rating (typically 10A or 15A).
Reconnect the battery terminal and test the radio.

3. Inspect Wiring Connections

Remove the radio unit using trim removal tools to access the back.
Check all wiring harness connections for looseness or damage.
Use a multimeter to test for voltage at the power connector; ensure it matches the specifications.
Reconnect any loose wires and secure the harness firmly.

4. Test Antenna Connection

Locate the antenna connection at the rear of the radio unit.
Ensure the antenna is securely connected; if loose, tighten it.
Inspect the antenna cable for any signs of wear or damage; replace if necessary.

5. Restore and Test

Reassemble the radio unit by reversing the removal steps.
Reconnect the negative battery terminal.
Test the radio functionality, including different audio sources and Bluetooth connectivity.
