These are unique to RSNAV S4 systems for your Audi. For example, many manufacturers claim that they support BT 5.0, but it means only the hardware is capable but no software to use BT 5.0, but work 2.1 compatible mode. RSNAV is the first manufacturer for Audi that offers full Bluetooth library. Also many advertises DSP function, but they rely on analog 2ch sound processing and losing much bass sound and interferences. Whereas RSNAV truly introducing I2S sound processing to eliminate unwanted noise interferences.
- Android 10
Indeed Android 10 sounds outdated whereas many offers Android 12 or up, but half of them are just fake Android 9 with 12 skin. Indeed, Some MediaTek devices indeed running Android 12 or up in the market. However, those MediaTek devices are half broken in terms of software perfection. RSNAV's Android 10 is the most polished system that is continuously updated for its life time. Qualcomm released Android 12 source codes for Snapdragon 665 platform thus OS version may be upgradable. However, OS upgrade is not an easy job as most Android OS version increment results in tighter security measures that hinders integrations with car system while providing minimal feature upgrade. RSNAV will look into free OS update if and only if such update deemed beneficial for drivers.
- AHD/CVBS Aftermarket HD class front/rear view camera support
