Troubleshooting GPS Issues in a 2020 Toyota Highlander

If the GPS in your 2020 Toyota Highlander is not functioning correctly, follow these detailed steps to diagnose and potentially fix the issue.

Step 1: Check for Basic Issues

Ensure the Vehicle is in an Open Area
- Park your Highlander in an open area away from tall buildings, trees, or tunnels that may obstruct satellite signals.
Restart the Infotainment System
- Turn off the vehicle and remove the key (or press the start button to turn off all electronics). Wait for about 5 minutes, then restart the vehicle.

Step 2: Verify Map and Software Updates

Check for Software Updates
- Connect the vehicle to Wi-Fi (if equipped) or use a USB drive with the latest software.
- Go to the settings on the infotainment system and navigate to the ‘Software Update’ section to check for available updates.
Map Updates
- Ensure your maps are up to date. If using a SD card for maps, check the Toyota website or consult your local dealer for the latest map version.

Step 3: Test the GPS Functionality

GPS Satellite Signal Check
- Navigate to the GPS settings and check if there is a signal strength indicator. Note if it shows any satellites detected.
Test Navigation
- Input a simple destination and observe if the GPS provides a route. If it does not, take note of any error messages.

Tools Required

OBD-II Scanner (optional for deeper diagnostics)
USB Flash Drive (for software updates)
Owner’s Manual (for reference)
Computer (for downloading updates)

Repair Instructions

Step 1: Reset the Infotainment System

If the GPS continues to malfunction after basic checks:

Locate the Reset Function
- Go to the "Settings" menu on the infotainment system. Look for "System" or "About".
Factory Reset
- Select the option for “Factory Reset” or “Reset to Default”. Confirm your choice. Note that this will erase saved preferences and settings.

Step 2: Check GPS Antenna

If the issue persists:

Locate the GPS Antenna
- Typically located on the roof of the vehicle, near the rear view mirror or integrated within the infotainment system.
Inspect the Antenna
- Check for any visible damage, corrosion, or loose connections. Ensure the antenna is securely connected.
Test Antenna Continuity (if necessary)
- Use a multimeter to check for continuity in the wiring connected to the GPS antenna.

Step 3: Consult with a Professional

If all previous steps fail:

Take the Vehicle to a Dealer or Certified Technician
- If you suspect a hardware issue or if the infotainment system still does not work after all troubleshooting, it may require professional diagnostics and repair.
Use OBD-II Scanner
- If available, use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) related to the infotainment system or GPS.

Optional: Updating GPS Software/Maps

Download Software/Map Updates
- Visit the official Toyota website or use the Toyota app to download the latest software or map files onto a USB drive.
Install Updates
- Insert the USB drive into the vehicle’s USB port and follow the prompts on the screen to install updates.

Conclusion

By following these steps, you should be able to identify and resolve most GPS-related issues in your 2020 Toyota Highlander. If the problem persists after exhausting these troubleshooting steps, seeking professional assistance is recommended to avoid further complications.
