1. BMW Optical Audio Codec:
BMW vehicles often use an optical digital audio (TOSLINK) connection to connect their premium audio systems. An optical audio codec is a device that converts digital optical audio signals into analog signals that can be processed by a traditional car audio system or connected to a new head unit.
It decodes high-quality digital audio signals transmitted over a fiber optic cable into digital signals. This allows you to connect new aftermarket devices such as an Android-based head unit to the BMW vehicle's audio system while maintaining high sound quality.
2. Android Screen:
The Android screen provides an interface for controlling various car functions (e.g., navigation, media, climate control) and allows for additional features such as touchscreen displays, smartphone mirroring, and app support.
Integration with BMW OEM audio system:
Depending on the vehicle, this allows the Android screen to control audio sources including radio, streaming or auxiliary inputs, while also integrating Bluetooth or USB connectivity.
Features:
Touchscreen interface: The Android screen provides a user-friendly interface to control music, maps and apps.
Bluetooth/USB integration: Depending on the system, you may be able to stream audio via Bluetooth or USB, giving you greater flexibility in your media options.
Apple CarPlay/Android Auto: These features often come with Android-based systems, allowing your smartphone to integrate seamlessly with the vehicle's display and audio system.
Video output/input: Some Android systems allow video playback via the main screen, providing additional functionality if you integrate a video input such as a rearview camera or external media source.
3. Why use this combination?
Integrating an Android screen with a BMW optical audio decoder is popular for the following reasons:
(1) Upgrading the infotainment system: If you want to replace the factory BMW system with a more modern Android interface, this setup allows you to maintain compatibility with your existing BMW audio system and audio decoder.
(2) Improved audio quality: With an optical decoder, you can take advantage of the high-quality digital audio of your Android system.
(3) Customization and functionality: Android-based systems allow for customization with apps, widgets, etc., and enable features such as navigation, music streaming, and voice assistants.
Conclusion:
The BMW Optical Audio Decoder and Android Screen combination essentially allows you to upgrade your BMW's infotainment system with modern Android features while ensuring compatibility with the original factory sound system. The decoder ensures that the high-quality optical audio signal is decoded and properly output to the vehicle's speakers. This combination enhances your driving experience by providing advanced features such as touchscreen control, media streaming, navigation, and integration with smartphone apps, while maintaining original BMW sound quality.
