Sync intervals are scans set in CoPilot to call CoPilot FleetPortal for updates. Additionally, CoPilot scans for updates at every navigation start up. Best practice is to determine the longest period of time during the day that the vehicle is going to be turned ON and CoPilot is actively running on the device.
Note: Local delivery is typically set to 1 hour and long haul fleets are set to 6 hours. This ensures that CoPilot will check at least once during the day in addition to startup.
