Solution

1. Preparation

Gather necessary tools: a laptop with Tesla service software (if needed), a USB drive for software updates, and internet access.
Ensure the vehicle is parked in a safe, well-lit area, and the battery is sufficiently charged.

2. Software Update

Connect the vehicle to Wi-Fi.
Navigate to "Software" in the settings menu and select "Check for Updates."
Download and install any available updates. Follow on-screen prompts to complete the installation.

3. Infotainment System Restart

While the vehicle is in Park, press and hold both scroll wheels on the steering wheel simultaneously.
Hold until the screen turns black and the Tesla logo appears, then release the scroll wheels.

4. GPS Signal Check

Open the navigation app and observe the map.
If the vehicle is not accurately positioned, check the GPS signal by moving the vehicle to an open area away from tall buildings or obstructions.
If the signal is still weak, inspect the GPS antenna for any debris or damage.
