In 2014, Apple announced something called CarPlay. At the time it wasn't met with much fanfare because to play it, you needed a radio in your car that most people didn't have. Today, many newer cars have it pre-installed; if you aren't one of the lucky ones, you can buy a compatible radio with CarPlay for less than $200--before installation.
Whether you are thinking about getting it or you want to know how to use it, this book will help you out.
