• Automatic Operation: If both units are set to automatic, a change in the active flight plan of one unit is also be seen in the other. Initiating a direct-to to a waypoint on one unit also initiates a direct-to to the same waypoint on the other unit. If one unit is set for automatic crossfill and the other is set for manual crossfill, then only the auto unit automatically sends data to the manual unit. In this configuration, the auto unit could be thought of as the master unit. • Manual Operation: If manual operation is desired, the pilot must invoke all transfers from that unit. When a unit is configured for automatic transfer, a manual transfer can also be done on command. If either of the messages 'data transfer error' or 'data transfer cancelled' are received during an automatic or manual transfer, the pilot must force another transfer. Transferring flight plans or user waypoints to/from a second 400/500-series unit: 1) Select 'Crossfill' from the Flight Planning Page, using the steps described at the beginning of this section. 2) The flashing cursor highlights the method field. Turn the small right knob to select 'Auto' or 'Manual' (Figure 9-23). 'Auto' automatically transfers any selection of (or any change to) a direct-to destination or active flight plan to a second 400/500-series Garmin unit.
