Inspect the fuses for any signs of damage; replace any blown fuses with the same amperage rating.

3. Inspect Wiring and Connections

Reconnect the battery and turn on the vehicle.
Access the infotainment system unit, usually located in the dashboard.
Visually inspect the wiring harness for any loose or disconnected connectors.
Look for any frayed or damaged wires; repair or replace as necessary.

Check Honda's official website or contact the dealership for the latest infotainment software version.
If an update is available:
- Download the update onto a USB drive.
- Insert the USB drive into the infotainment system's USB port.
- Follow on-screen prompts to complete the update process.
