Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the fuse related to the radio/audio system.
Use a fuse puller or pliers to remove the fuse and check for a break in the filament.
If the fuse is blown, replace it with a new fuse of the same amperage rating (consult the owner's manual for specifications).

3. Reset the Radio

Reconnect the negative battery terminal after ensuring all connections are secure.
Turn on the ignition without starting the engine.
Press and hold the power button on the radio for about 10 seconds or follow the specific reset sequence from the owner’s manual.

4. Reprogram the Radio (if needed)

If the radio still displays "Safe" or "Locked", follow the steps in the owner's manual to input the radio’s security code (usually provided with the vehicle documentation).

5. Test the Radio

Once the radio is reset and any necessary programming is done, turn the vehicle on and test the radio for functionality.
Ensure that all functions, including Bluetooth and media inputs, work properly.
