S4 standard features

- Wireless/wired CarPlay

- Wireless/ wired Android Auto

- Bluetooth phone call/Music streaming

- MP4 video playback

- Plug and Play 


It is Linux based, thus no Android App can be installed or run natively. 

S4 Standard cannot be upgraded to Pro or Ultimate as they are totally different hardware. Only the main wire may be compatible with Pro or Ultimate.

S4 standard no longer supports CVBS low resolution rear/front camera. It only supports AHD 720P 25Hz rear/front camera. 


Sound quality is better than our standalone smart interface kit and as good as our RSNAV S4 pro/ultimate with Rohm BU321 series DSP. Nevertheless, BU321 and TDA7729 have different characteristic. BU321 is digital audio operating based on i2s with high resolution, prominent high frequency responses.  TDA7729 is analog audio processor with profound bass.
