Maintenance
To ensure optimal performance and longevity of your MSXTTLY adapter, consider the following:
- Heat Management: While the adapter features a heat dissipation design, it is normal for it to become warm during use. For optimal cooling, especially during extended use or in hot environments, we recommend using the provided extension cable and placing the adapter near an AC vent in your car.
- Firmware Updates: Periodically check for firmware updates to ensure the best compatibility and performance. Instructions for updating are typically found in the user manual or on the manufacturer's support website.
Troubleshooting
If you encounter issues with your MSXTTLY adapter, please refer to the following common solutions:
- Compatibility Check: Ensure your car is equipped with OEM wired CarPlay or Android Auto (2017+ models) and your phone meets the OS requirements (iOS 10+ for iPhone, Android 11.0+ for Android).
- Bluetooth & Wi-Fi: Confirm both Bluetooth and Wi-Fi are enabled on your phone and not connected to other devices during pairing. Do not pair the Wi-Fi or enter a Wi-Fi password while connected to the adapter.
- Connection Stability: Connection stability can be affected by environmental signal strength. If issues persist, try restarting both your phone and your car's infotainment system.
- Adapter Not Recognized: If the car does not recognize the adapter, ensure it is plugged into the correct data transmission USB port, not just a charging port. The adapter's indicator light should illuminate.
- Audio Issues: If there is no sound during phone calls, check the "Audio" settings in CarPlay/Android Auto and ensure no other Bluetooth devices are interfering.
- Screen Freezes/Unable to Load: Try unplugging the adapter, resetting your car's radio, and restarting the car. You may also need to "Forget" the "smartBox-xxxx" Bluetooth device from your phone's settings and reconnect.
