Please remember a crucial safety rule for Bluetooth connections. You must move the map marker near your actual physical location before changing your GPS coordinates. Teleport Mode may fail if you move more than 15 km in a single jump. For games and location apps we highly recommend using One stop mode or Multi stop mode instead.
