Car components talk via CAN bus. There are many aftermarket head units that includes CAN bus support and has presets to talk and retrieve information from multiple car models (climate control, lights, speed, engine status, etc). The problem is, most cars manufactured in the past several years don't allow aftermarket head unit installation anymore, so you're basically stuck with whatever entertainment system the car manufacturer put in the car for the rest of the car's life.
