Anautomotive head unit, sometimes called theinfotainment system,[1] is avehicle audio 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, carreceiver, 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 thedashboard 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), USBMP3,dashcams,GNSS navigation,Bluetooth,Wi-Fi, and sometimes vehicle systems status. Moreover, it may provide control of audio functions including volume, band, frequency, speaker balance, speaker fade, bass, treble,equalization, and so on.[2] With the advent of dashcams, GNSS navigation, andDVDs, head units with video screens are widely available, integratingvoice control andgesture recognition.
An original standard head unit size isISO 7736, developed by theDeutsches Institut für Normung (DIN):
Single DIN (180 mm × 50 mm or 7.09 in × 1.97 in) in Europe, South America, and Australasia
Double DIN (180 mm × 100 mm or 7.09 in × 3.94 in) in Japan, the UK, and North America.
For both single and double DIN units, ISO 10487 is the connectors standard for connecting the head unit to the car's electrical system.[4]
