2. Screen Care
Clean the touchscreen with a soft, lint-free cloth. For stubborn smudges, lightly dampen the cloth with water or a screen-safe cleaner. Avoid abrasive materials or harsh chemicals that could damage the screen coating.

- Date/Time Incorrect: The device's date and time are updated automatically when connected to the GPS module. Ensure the GPS module is properly connected and has a clear view of the sky.
- Bluetooth Connection Issues: If experiencing difficulty pairing with your phone or helmet, ensure both devices are in pairing mode and within range. Avoid connecting your phone to a Bluetooth helmet or headset directly while attempting to pair with the CarPlay screen, as this may interfere with the process.
