Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked in a safe location and the ignition is off.
Disconnect the vehicle battery to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the fuse associated with the navigation system (refer to the owner's manual for the exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; if the wire is broken or the fuse is blackened, replace it with a new fuse of the same amperage.

Visit the Toyota official website or contact a Toyota dealer to check for available updates for the navigation system.
Download the update files onto a USB flash drive (ensure it is formatted to FAT32).
Insert the USB drive into the USB port of the vehicle and follow the on-screen instructions to update the software.

Reconnect the vehicle battery.
Start the vehicle and allow the navigation system to boot up.
If the system remains unresponsive, perform a factory reset by navigating to the settings menu (consult the owner's manual for specific steps).

5. Reconnect Battery

Ensure all connections are secure before reconnecting.
Reconnect the battery terminals, starting with the positive terminal first, followed by the negative terminal.
