Solution

1. Preparation

Ensure the vehicle is parked and in a safe location.
Disconnect any devices connected to the USB ports.
Gather tools: a USB drive for software update (if necessary).

2. Update Software

Go to the “Software” tab in the infotainment menu.
Check for any available updates and follow on-screen prompts to download and install.
If an update is available, allow the vehicle to install it (this may take some time).

3. Perform a Hard Reset

Ensure the vehicle is in a safe location.
Press and hold both scroll wheels on the steering wheel for approximately 10 seconds until the screen turns off and the Tesla logo appears.
Wait for the system to reboot fully before checking functionality.

4. Check 12V Battery

Using a multimeter, measure the voltage of the 12V battery.
If the voltage is below 12.4V, consider replacing the battery as it may not be providing sufficient power to the infotainment system.

5. Component Inspection

If issues persist, inspect the infotainment unit's connections behind the screen.
Remove any panels if necessary to access the infotainment unit and check for loose connectors or damaged wiring.
Reconnect any loose connections securely.

6. Factory Reset (if necessary)

If all else fails and the screen continues to freeze, navigate to "Settings" -> "Service" -> "Factory Reset" to restore to factory settings. Note that this will erase all personal settings.
