Connect to Your Car
You can connect to your Car with an Apple Watch, assuming you own a new and expensive one from Tesla or BMW. Apple showed a BMW app on stage that lets you know the range of the BMW i, charging status and if the doors are locked.
Hyundai offers an Apple Watch app to remote start and unlock your doors from your wrist. Viper SmartStart lets you control aftermarket car starters and unlock your car. There are unofficial Tesla Apple Warch apps that let you control many car features and Volvo On Call includes support to start, unlock and more.
Most Apple Watch apps for your car include the ability to honk the horn, flash the lights and even see fuel or battery range.
