Automatic Pro tracks the location of your car using the built in 3G connection and GPS. Live location tracking is only available in the Automatic app.
When you first open the app, you'll either see a banner that says Driving for "X" or Parked "X" Days/Hours/Minutes ago.
Selecting that will take you to a screen where you can see your car's last known location. If you're driving, this location updates about every 20 seconds. You can also share your car's location for a specific duration by selecting the SHARE LIVE LOCATION button.
