If you want to use Android Auto Head Unit while travelling in your car to make driving easier and less distracted, you’ll need a supported smartphone and a car that supports it. By that, we mean your car must have an infotainment system that has support for Android Auto, without which you won’t be able to use it. While most modern cars come with Android Auto support on the car stereo, some older cars may not have this built-in. In such a case, the best option is to replace the infotainment system in your car with a new Android Auto head unit.
