Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, and a flat-head screwdriver.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace the Radio Fuse

Locate the fuse box, which is typically found under the dashboard or in the engine compartment.
Use the socket set to remove the fuse box cover.
Identify the fuse designated for the radio using the diagram on the fuse box cover.
Pull the fuse out using pliers and inspect it for continuity. If it’s blown, replace it with a new fuse of the same amperage (typically 15A).
Reinstall the fuse box cover and reconnect the battery.

3. Check Radio Connections

If the fuse is intact, remove the radio unit from the dashboard using the flat-head screwdriver to pry off the trim carefully.
Disconnect the radio from its harness by gently pulling the connectors apart.
Inspect the connectors for corrosion or damage. Clean or replace as necessary.
Reconnect the harness securely and reinstall the radio into the dashboard.

4. Perform a Soft Reset

After reconnecting the radio, disconnect the battery again for 10 minutes.
Reconnect the battery and check if the radio powers on.

5. Software Update

Use an OBD-II scanner to check for any error codes related to the infotainment system.
If necessary, follow the manufacturer’s instructions to update the radio software via USB or through the vehicle's infotainment settings.
