ISO 7736

International standard ISO 7736 defines a standard size for car audio head units and enclosures. The standard was originally established by the German standards body Deutsches Institut für Normung as DIN 75490, and is therefore commonly referred to as the "DIN car radio size". It was adopted as an international standard in 1984.

Head units generally come in either single DIN (180 x 50 mm panel) or double DIN (180 x 100.3 mm panel) size. The depth is not standardized; as a result, some cars such as the Opel Manta / Ascona have the correct sized front aperture but will accommodate few DIN sized radios other than the original due to the shallow depth; this despite the vehicle being manufactured as late as 1988. The US standard for a DIN radio is 6.83" x 2" (although the actual 180 mm width converts to something like 7-3/32" so most people use 7-1/8" to allow for clearance) and the Double DIN sized radio is a 7" x 4". Some radios in Japanese Kei cars do not conform to the DIN standard however.

Removal tools

For removing the unit, a pair of U-shaped devices are often used. The devices are inserted in the two pairs of holes, at either end of the stereo fascia, the action releasing the unit from the mounting and providing a pair of handles to pull the unit free. These tools vary from manufacturer to manufacturer. Becker uses a pair of key-shaped removal tools, with one hole each. Often a set of thin screwdrivers will work just as well.

Antiquated names for head unit are receiver, in-dash stereo or dash stereo.

Connectors for car audio

Several types of connectors for car audio systems are used.

Vehicle audio

Vehicle audio is equipment installed in a car or other vehicle to provide in-car entertainment and information for the vehicle occupants. Until the 1950s it consisted of a simple AM radio. Additions since then have included FM radio (1952), 8-Track tape players, Cassette Players, CD players (1984), DVD players, Blu-ray players, navigation systems, Bluetooth telephone integration, and smartphone controllers like CarPlay and Android Auto. Once controlled from the dashboard with a few buttons, they can now be controlled by steering wheel controls and voice commands.

Initially implemented for listening to music and radio, vehicle audio is now part of car telematics, telecommunication, in-vehicle security, handsfree calling, navigation, and remote diagnostics systems. The same loudspeakers may also be used to minimize road and engine noise with active noise control, or they may be used to augment engine sounds, for instance making a smaller engine sound bigger.
