head unit(redirected from Headunit)
head unitThe control center and user interface for an automobile's information and entertainment center, which typically resides in the center of the dashboard. Also called a "receiver," the head unit provides the main controls for the radios (any combination of AM, FM, SiriusXM, HD Radio) as well as a CD/DVD player, GPS navigation, Bluetooth cellphone integration and music storage. In new vehicles, several head unit controls, such as volume, answer/hang up and switch channel are duplicated with buttons on the steering wheel.
The head units have their own amplifiers for powering the speakers, but may have optional outputs for more powerful, stand-alone amplifiers. They may also have inputs for smartphones (see CarPlay and Android Auto). See in-dash navigation.
