Sub-step 1: Locate the fuse box (usually under the dashboard or in the engine compartment).
Sub-step 2: Identify the fuse for the infotainment system using the fuse diagram.
Sub-step 3: Remove the fuse and visually inspect it; replace it if blown (use the same amperage rating).

4. Perform Soft Reset

Sub-step 1: Disconnect the negative battery terminal and wait for at least 5 minutes.
Sub-step 2: Reconnect the negative battery terminal securely.
Sub-step 3: Turn on the ignition and check if the infotainment system powers up.

5. Inspect Wiring Harness

Sub-step 1: Remove the trim panel surrounding the infotainment system.
Sub-step 2: Check the wiring harness connections behind the unit; ensure they are secure.
