head unit
The 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.Self-Contained
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.
