I'm still learning the process of using Data Base Concierge and the Flightstream 510 to update the GTN 750 and G500. I know that the Flightcharts data base takes quite a while to synch from the GTN 750 to the G500. Today being a beautiful day to fly (they're all great days to fly, this was even better) I figured it would be a crime not to gather some helpful information. The Flitecharts update was 868 MB. It took a few minutes to upload to the GTN 750 via wifi (didn't time it, but subjectively not overly long). I then flew around the area, periodically checking the progress of the synch on the data base page of the G500. Bottom line: It took about 45 minutes of flight time for the synch to complete. Of course, once it's completed the G500 needs to be restarted to finish the process. So unless you're VfR and feel like flying for few minutes on your backup instruments and Nav this needs to wait until the next flight.
Here are my questions: Is 868MB a typical size for a Flitecharts update? Is 45 minutes about what others are seeing for the time for the synch process to complete?
