    • Follow the instructions to copy the update to a USB drive.
    • Insert the USB into the USB port of your Highlander.
    • Turn on the ignition (do not start the engine) and follow the prompts on the screen.

Step 2: Soft Reset the System

  1. To Reset:
    • Turn off the vehicle and remove the key.
    • Wait for 10 minutes.
    • Restart the vehicle and check if the navigation system responds.

Step 3: Inspect Connections

    • Reconnect any loose connectors.

Step 4: Diagnose with OBD-II Scanner

  1. Connect OBD-II Scanner:
    • Plug the scanner into the OBD-II port (usually located under the dashboard).
    • Turn on the ignition and scan for error codes.
    • Address any error codes related to the infotainment system.

Step 5: Battery Check

  1. Using a Multimeter:

Final Steps
