Head unit意思

"Head unit" is a term commonly used in the automotive industry to refer to the main in-dash component of a vehicle's audio system. It is the central control unit for the audio and sometimes other electronic systems in a car, truck, or other vehicle. The head unit typically includes a radio receiver, CD player, DVD player, or other media playback capabilities, as well as controls for volume, station selection, and other audio functions. It may also include features such as a touchscreen display, GPS navigation, Bluetooth connectivity, and smartphone integration. The head unit is often removable for security purposes, and it can be replaced with an aftermarket unit to upgrade the vehicle's audio system.
