Synchronization (Dual Installations Only)

Dual GDU 620 units when connected in the aircraft may be set up to
communicate and share information by "Crossfilling" or synchronizing
information between the two units.
When Barometric Correction is synchronized, any changes to the Barometric
Setting on either GDU will change it on both GDUs.
Crossfill synchronization for CDI and Baro Corrections are selected in Aux
mode.
1) While viewing the first page of the AUX page group, press the small MFD
knob and turn the large MFD knob to highlight "CDI" or "BARO" in the
"Synchronization" box in both units.
2) Turn the small MFD knob to select "ON" or "OFF."
3) Press ENT.
