A Car DVD player, also known as a Car Radio, Car Multimedia System, or Car Infotainment System, typically comes in the form of a touchscreen or display mounted in (or on) the dashboard in the center of the car.
Beyond just offering entertainment and information, these systems often act as the central hub for controlling a myriad of car functions, they allow you to listen to the radio, use optional GPS navigation, connect to cellphone with Bluetooth, and check important stuff like tire pressure. Over recent years, these displays have expanded in size, some even as big as home tablets.
While most cars come equipped with OEM radio options, the pursuit of improved sound quality and additional features has made aftermarket radios a popular trend.
