Many users encounter challenges when trying to connect OBD2 dongles to their Android car radios, particularly with brands like Eonon. If you’re struggling to get your OBD2 app working on your Eonon head unit, you’re not alone. This article explores common problems and potential solutions to help you establish a connection and utilize your OBD2 functionality.
One frequent issue arises during Bluetooth pairing. Users often find that while their OBD2 dongles work seamlessly with phones and tablets, the Eonon car radio refuses to pair correctly. The typical pairing process involves entering a PIN code, but sometimes, the system may reject valid codes or exhibit unexpected behavior during the input process. As one user described, even when manually setting the Bluetooth code and attempting to pair, the system might abruptly state “code is not correct,” even when entering the correct PIN like ‘1234’ or ‘0000’.
This problem can manifest with various OBD2 dongles, including popular models like the KONNWEI KW902 and vgate iCar Pro OBD2 Bluetooth 4.0 (BLE). These dongles are generally reliable and compatible with numerous devices, making their failure to connect to an Eonon Android radio particularly frustrating.
Possible reasons for these connection difficulties can range from Bluetooth configuration issues within the Android car radio’s settings to compatibility problems between the specific OBD2 dongle and the Eonon system’s Bluetooth module or software. Sometimes, hidden Bluetooth settings within the Android system might require adjustments beyond the standard pairing procedure.
To troubleshoot, consider the following steps:
- Verify Bluetooth Settings: Double-check the Bluetooth settings on your Eonon car radio. Look for any advanced or hidden settings that might affect pairing, such as specific PIN code requirements or auto-connect options.
- Test Different PIN Codes: While ‘0000’ and ‘1234’ are common, try other standard PIN codes in case there’s an unexpected default setting.
- Disable Auto-Connect Temporarily: As mentioned by a user, disabling “auto-connect” can sometimes allow for manual PIN entry during pairing.
- Check OBD2 App Compatibility: Ensure that the OBD2 app you are using is compatible with Android car radios and specifically with Eonon devices if possible. Some apps might have specific Bluetooth protocols or connection methods.
- Restart Devices: A simple restart of both your Eonon car radio and your OBD2 dongle can sometimes resolve temporary glitches affecting Bluetooth connectivity.
- Dongle Compatibility: While models like KONNWEI KW902 and vgate iCar Pro are generally compatible, there might be specific firmware versions or hardware revisions that could cause issues with certain Android car radios. Research if other users have reported success with your specific dongle model and Eonon radios.
If you continue to experience issues, consulting Eonon’s support documentation or online forums dedicated to Eonon Android car radios might provide further insights and solutions from other users who have overcome similar OBD2 connection challenges.
