6. Troubleshooting
If you encounter issues with your XTRONS CP03 dongle, please refer to the following troubleshooting steps:
| Problem | Possible Cause | Solution |

| Dongle not recognized by car stereo. | Loose USB connection, incompatible car stereo, AutoKit app not installed/running. | Ensure the dongle is firmly plugged into the car stereo's USB port. Verify your car stereo is Android 7.1+ and the AutoKit app is installed and open. Try a different USB port if available. |
| iPhone CarPlay wireless connection fails. | Bluetooth/Wi-Fi off on iPhone, incorrect pairing, dongle not powered sufficiently. | Check iPhone's Bluetooth and Wi-Fi settings. Re-pair Bluetooth with the CP03. Ensure the dongle is receiving adequate power from the USB port. |
| Android Auto not connecting (wired). | Incorrect cable, Android Auto app not installed/updated, phone settings. | Use a high-quality USB cable. Ensure the Android Auto app is installed and updated on your phone. Check your phone's USB connection mode (e.g., set to File Transfer/Android Auto). |
| Audio cuts in and out or is distorted. | Loose cable connections, interference, software glitch. | Check all USB and phone cable connections. Restart the AutoKit app and your phone. Ensure no other devices are causing electrical interference. |
| App (AutoKit/Android Auto) crashes frequently. | Software conflict, outdated app version, insufficient system resources. | Ensure the AutoKit app on your car stereo and Android Auto app on your phone are updated to the latest versions. Try reinstalling the AutoKit app. Clear cache for the apps. |
