What is the purpose of HDMI in a car?

[JackLee]

HDMI in a car stands for High-Definition Multimedia Interface. After connecting to the HDMI port, it can simultaneously transmit both audio and video signals. By connecting your phone to the car's HDMI port, you can synchronize your phone's screen with the vehicle's central control screen. This allows you to play videos and music from your phone on the car's screen, as well as project your phone's navigation onto the display. Requirements for connecting your phone to the car's screen: 1. The phone must support MHL; 2. The car must have an HDMI port; 3. You need an MHL data cable. Simply plug in the corresponding ports, and both the phone and the car's screen will prompt that they are connecting. No additional drivers need to be downloaded. Wait a few seconds, and your phone's screen will be projected onto the car's display. If there is no response, try restarting your phone.
