I have a subscription with Jeppesen to update my data cards for my 430W. I haven't used fly.garmin to update, but assume it works the same as the Jepp subscription. The Jepp software programs the card directly. The 430/530 cards are not readable directly by a computer. Can anyone explain to me how someone that has a legitimate subscription to update a 430/530 can update the database? It seriously limits the use of this software when the navdata is out of date.
Thank you!
