In order for the device to properly show/track, make sure that the device is on. Make sure that the unit is fully charged and the green cell data light is blinking. We suggest placing it on the dashboard of a car and taking it for a drive for 20-30 minutes. It is important that it has a clear, unobstructed view of the sky. Since the device is motion-activated, it is not sufficient to leave it outside or on a window sill for it to register. It must be moving in order to register and report its location.
