Solution

1. Preparation

Ensure the vehicle is parked safely and on a level surface.
Gather necessary tools: smartphone or tablet for Wi-Fi testing, and access to Tesla app for updates.
Ensure the vehicle battery is adequately charged.

2. Software Update

Go to the main screen in the vehicle and select "Software" from the menu.
Check for any available updates. If an update is available, connect to a Wi-Fi network.
Follow the prompts to download and install the update. This may take time; ensure the vehicle remains parked during this process.

3. Infotainment System Restart

While parked, press and hold both scroll wheels on the steering wheel until the screen goes black.
Wait for a few moments until the Tesla logo appears and the system reboots.
Once the system reboots, check the navigation functionality.

4. Verify GPS Functionality

Access the "Settings" menu, then navigate to "Navigation" and check the GPS signal strength.
Ensure that there are no obstructions (e.g., tall buildings or trees) blocking the GPS signal.
If signal strength is low, consider moving the vehicle to an open area.

5. Factory Reset (if necessary)

Go to "Settings" > "Service" > "Factory Reset."
Follow the prompts to confirm the factory reset.
Note: This will erase all saved data and settings, so be prepared to reconfigure the navigation system afterward.
