Hi Olga. Which adapter did you buy? Here's a FAQ that shows you how to tell the difference if you're not sure.
If you purchased Automatic Pro, it has a 3G cellular connection and you do not need to have a Bluetooth connection in order to know where the car is at any moment. However, if you purchased Automatic Lite then, yes, it does require a BT connected phone to be present in the car and won't show the trip until after it ends.
