Garmin GTN XI Series Manual page 16

Tapping Skip Transfer and Continue cancels any unfinished wireless transfers and
initiates the update process.
The unit activates any databases that completed transfer before the interruption.
Previously selected databases on an SD card or in the internal standby update as well.
Database Concierge transfers
databases from the app to
Flight Stream 510. A progress
bar shows when this process is
complete.
GTN Xi either updates or
preloads databases based on
their effective date. A second
progress bar indicates upload
status.
The unit automatically restarts
upon database activation.
