Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools (socket set, screwdrivers).
Ensure the vehicle is parked safely and the ignition is off before starting.

2. Update Software

Visit the official Toyota website or contact the dealer for the latest software updates.
Download the update to a USB flash drive if required.
Insert the USB into the vehicle's USB port and follow on-screen instructions to install updates.

3. Reset the System

Disconnect the negative terminal of the battery using a socket wrench.
Wait for at least 10 minutes to ensure all systems are fully powered down.
Reconnect the battery terminal and tighten it securely.

4. Inspect and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse for the navigation system (refer to the owner’s manual for the exact location).
Use a multimeter to check if the fuse is functioning. If blown, replace with a fuse of the same amperage.

5. Check Wiring Connections

Remove the head unit from the dashboard using appropriate tools (screwdriver or trim removal tool).
Inspect the wiring harness for any visible damage or loose connections.
Reconnect any loose wires and ensure all connectors are securely fastened.
