An Apple CarPlay or Android Auto unit, often referred to as a head unit, is a smart in-car system that seamlessly integrates your smartphone with your vehicle’s infotainment display. These units allow drivers to access and control key smartphone apps—such as navigation, music streaming, phone calls, messaging, and even voice assistants—directly from the car’s touchscreen or through voice commands. This hands-free connectivity not only enhances convenience but also significantly improves safety by minimizing distractions on the road. Whether you’re navigating with Google Maps, streaming your favorite playlist, or responding to texts, these systems help you stay connected while keeping your focus on driving.
