Solution

1. Preparation

Ensure the vehicle is parked safely and turned on.
Have the vehicle's user manual available for reference.
Ensure your smartphone is paired with the vehicle for potential updates.

2. Check for Software Updates

Access the "Software" tab on the main display.
Look for any available updates and follow prompts to install them.
Ensure the vehicle is connected to Wi-Fi for larger downloads.

3. Perform a Soft Reset

Press and hold both scroll wheels on the steering wheel until the touchscreen turns off.
Release the scroll wheels and wait for the Tesla logo to appear.
Allow the system to reboot fully, which usually takes less than a minute.

4. Inspect GPS Antenna

Open the rear trunk and locate the GPS antenna, usually near the rear glass.
Ensure it is securely attached and free from obstructions (like debris or aftermarket installations).
If damaged, replace with a genuine Tesla GPS antenna.

5. Verify Internet Connection

Go to "Controls" > "Wi-Fi" and check if the vehicle is connected to a network.
If not connected, select your Wi-Fi network and enter the password.
If the connection is unstable, consider moving closer to the router or using a mobile hotspot.
