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, 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, and DVDs, head units with video screens are widely available, integrating voice control and gesture recognition.

Size standards

An original standard head unit size is ISO 7736, developed by the Deutsches 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]

Aftermarket brands

Manufacturers offer DIN headunits and standard connectors (called universal headunits), including Pioneer, Sony, Alpine, Kenwood, Eclipse, JVC, Peach Auto (Hong Kong), Boyo, Dual, Visteon, Advent and Blaupunkt.
