Many users encounter difficulties when attempting to pair an OBD2 scanner with their Android car radio. This issue prevents them from utilizing real-time vehicle diagnostics and performance monitoring directly on their in-car entertainment system. This article addresses common problems and potential solutions for connecting your OBD2 scanner to your Android device in your car.
One user shared their experience trying to connect various OBD2 dongles, including KONNWEI KW902 and vgate iCar Pro OBD2 Bluetooth 4.0 (BLE), to a 10″ Android 10 car radio. Despite successfully pairing these dongles with phones, tablets, and laptops, they faced persistent failures with the car radio. The user attempted to manually input pairing codes in Bluetooth settings, even disabling auto-connect features, but the system repeatedly rejected the correct codes, displaying “code is not correct” errors.
This pairing problem can stem from several factors. Sometimes, the issue lies within the Bluetooth compatibility between the specific OBD2 scanner and the Android car radio’s Bluetooth module. Some car radios might have limitations or specific protocols that are not universally compatible with all OBD2 scanners. Another potential cause could be software glitches within the Android car radio’s operating system, particularly in how it handles Bluetooth connections for OBD2 devices. It’s also worth checking if there are any firmware updates available for the car radio that might address Bluetooth connectivity issues.
To troubleshoot, ensure both your OBD2 scanner and Android car radio support the same Bluetooth protocols. Consult the manuals for both devices to confirm compatibility. Try resetting the Bluetooth settings on both devices and attempting the pairing process again. In some cases, using a different OBD2 scanner model or a different Android car radio might be necessary to achieve a stable connection. Online forums and communities dedicated to car audio and Android car radios can also provide valuable insights and user-specific solutions for these pairing challenges.
