Starting today, Tuesday, Hyundai vehicle owners who subscribe to the Blue Link connectivity service will be able to sign up to use it in conjunction with Amazon Echo. You can call your car hands-free from inside the house on a cold morning, start the car and have it all warmed up by the time you go outside. Owners can also lock or unlock their cars, flash the lights and perform other functions by voice. You just call Alexa by name to get the system’s attention, then issue a command.
