Knowing how to get where you're going is vital when driving, which is why in-dash navigation systems have made paper maps almost obsolete. And nav systems have gotten better with cloud connectivity, allowing for real-time traffic info, local search, and compatibility with portable devices. However, these days we all have an advanced GPS in our pocket in the form of a smartphone. Apple CarPlay and Android Auto let you use your phone's map system of choice on the dashboard screen, which is often more accurate and up-to-date than some navigation systems.
