It is usually installed on the center console between the main driver and the co-driver, close to the main driver. With the rapid development of smart devices in recent years, the functions of the central control screen have become more and more powerful. Many of them integrate entertainment functions such as video playback and games. On the one hand, the main driver will use the central control screen to perform driving control operations such as navigation during driving.
