Troubleshooting Bluetooth Connectivity Issues in a 2020 Toyota Highlander
Tools Required
  • Smartphone or Bluetooth-enabled device
  • Owner’s manual for the Toyota Highlander
  • Access to Wi-Fi for software updates (if necessary)
  • OBD-II scanner (for advanced diagnostics, if needed)
Repair Instructions

Step 1: Check Vehicle Bluetooth Settings

  1. Turn on the ignition without starting the engine.
  2. Navigate to the Home screen on the infotainment display.
  3. Select Setup > Bluetooth.
  4. Ensure Bluetooth is turned ON. If it is OFF, turn it ON.

Step 2: Check Device Bluetooth Settings

  1. On your smartphone, go to Settings > Bluetooth.
  2. Ensure Bluetooth is turned ON.
  3. Look for any available devices to connect to; if the Highlander is not listed, continue to the next step.

Step 3: Clear Previous Pairings

  1. On the infotainment system, go to Setup > Bluetooth > Paired Devices.
  2. Select any previous devices and choose to Delete or Forget each one.
  3. On your smartphone, also remove the Highlander from the list of paired devices.

Step 4: Pair the Device Again

  1. On the Highlander, go back to the Bluetooth settings.
  2. Select Add New Device.
  3. On your smartphone, ensure it is in pairing mode (this is usually automatic when accessing the Bluetooth settings).
  4. Wait for the Highlander to appear on your smartphone’s list of available devices and select it.
  5. Confirm the pairing code that appears on both the smartphone and the vehicle’s screen (if prompted).
  6. Once connected, test the audio by playing music or making a call.

Step 5: Perform a Software Update

  1. Check the owner’s manual for instructions on updating the infotainment system.
  2. If necessary, connect the vehicle to a Wi-Fi network via the infotainment system.
  3. Navigate to Setup > System Update and follow the prompts to download and install any available updates.
  4. Restart the vehicle’s infotainment system after the update is complete.

Step 6: Check for Interference

  1. Turn off any other Bluetooth devices that are not in use.
  2. Move the smartphone closer to the vehicle’s Bluetooth receiver (usually located near the center console).
  3. Try to reconnect and test if the issue persists.
Additional Considerations
  • If the problem continues despite following these steps, consider resetting the infotainment system to factory settings, but back up any personal data or settings beforehand.
  • Consult with a Toyota dealer or a qualified technician if issues persist. They can run diagnostics using an OBD-II scanner to check for any faults in the Bluetooth system.
Conclusion

By following these detailed steps, you should be able to resolve most Bluetooth connectivity issues in your 2020 Toyota Highlander. If problems persist, professional assistance may be necessary to explore hardware issues or advanced software diagnostics.
