Solution

1. Preparation

Gather necessary tools: socket set, multimeter, OBD-II scanner, and a flathead screwdriver.
Ensure the vehicle is parked on a level surface and the keys are removed from the ignition.

2. Check Fuses

Locate the fuse box under the dashboard or hood.
Remove the fuse for the radio using the fuse puller.
Inspect the fuse visually; replace it if blown.
Reinsert or replace the fuse and test the radio.

3. Inspect Wiring Connections

Remove the radio trim panel using a flathead screwdriver to avoid damage.
Unscrew the radio unit from its mounting bracket.
Check the wiring harness connections at the back of the radio for tightness and any signs of corrosion.
Clean any corroded connections and ensure all plugs are securely connected.

4. Test Radio Functionality

Reconnect the battery if it has been disconnected.
Turn on the ignition and power on the radio.
If the radio is still non-functional, consider replacing the radio with a compatible aftermarket or OEM unit.

5. Programming/Resetting

If an aftermarket radio is installed, follow the manufacturer's instructions to program the radio.
If a soft reset was performed earlier, verify if it resolved the issue; if not, consult the dealership for possible software updates.
