Automotive head unit
An automotive head unit is an automotive infotainment component providing a unified hardware interface for the system, including screens, buttons and system controls for numerous integrated information and entertainment functions.
Other names for automotive head units include car stereo, car receiver, deck, in-dash stereo, and dash stereo.
Central to a vehicle's sound and information systems, head units are located prominently in the center of the dashboard or console, and provide an integrated electronic package.
The head unit provides a user interface for the vehicle's information and entertainment media components: AM/FM radio, satellite radio, DVDs/CDs, cassette tapes (although these are now uncommon), USB MP3, Dashcams, GPS navi, Bluetooth, WiFi, and sometimes vehicles systems status — and may provide control of audio functions including volume, band, frequency, speaker balance, speaker fade, bass, treble, EQ and so on. With the advent of dashcams, GPS navigation and DVDs, head units with video screens are widely available, integrating voice control and gesture recognition.
