The ELD will only report the GPS location when it is powered. The “Last Known Location” is recorded and an 'Unplugged' alert is sent in this event. When the ELD is plugged in again, it should start collecting data when the vehicle engine is running. If not, please check the lights on the ELD for power status. Please contact FleetUp Support at support@fleetup.com or call 855-274-2886 option 3 for more information.
