A year after Apple launched CarPlay, Google followed suit with its own platform, Android Auto. If you own a compatible car and an Android smartphone, getting started with Android Auto is probably one of the best things you can do for your everyday commutes. Supported car models take this convenience a step further by enabling you to use Android Auto wirelessly. It's fair to assume that wireless Android Auto works over Bluetooth — and you'd be right, except that's only half true. This is why getting in your car turns on your phone's Wi-Fi automatically.
