    • Check if the car charger is properly connected to both the device and the vehicle's power outlet.
    • Ensure the vehicle's cigarette lighter socket is functioning.
    • Try a different power source if available.
  • Recording issues (e.g., stops recording, corrupted files):
    • Ensure a Class 10 or higher speed Micro SD/TF card is used.
    • Format the memory card regularly.
    • Replace the memory card if issues persist, as it might be faulty.
  • CarPlay/Android Auto not connecting:
    • Ensure your phone's Bluetooth and WiFi are enabled.
    • Check that your phone's operating system meets the minimum requirements (Android 11+ for Android Auto).
    • Restart both the K4 unit and your smartphone.
    • Ensure no other devices are interfering with the wireless connection.
  • GPS tracking not working:
    • Ensure the optional GPS antenna is properly connected and placed with a clear view of the sky.
