Disconnect the negative battery terminal to prevent any electrical issues.

2. Soft Reset the Infotainment System

Reconnect the battery terminal temporarily.
Hold the power button on the infotainment system for 10 seconds until the system restarts.

3. Inspect Wiring and Connections

Remove the infotainment system unit from the dashboard using a trim removal tool.
Visually inspect the wiring harness for any signs of wear, fraying, or loose connections.
Secure any loose connections and repair any damaged wires with electrical tape or connectors.

4. Update Software

Visit the Toyota website or consult the dealership for the latest infotainment software.
Download the updates onto a USB flash drive (if applicable).
Insert the USB drive into the infotainment system and follow on-screen prompts to update.

5. Check Battery Voltage

Using a multimeter, check the battery voltage. It should be between 12.4V and 12.7V.
If the voltage is low, consider recharging or replacing the battery, as insufficient power can lead to system malfunctions.
