Does anyone know the format of the data cards for the GNS 530? Our club is
putting them in our small fleet, and we are considering buying extra data
cards to make the updates easier. The Garmin price seems high. If these are
standard cards, we may be able to do better elsewhere. Anyone have any
experience to share?

The license for the navdata is for one unit. If you figure out how to
distribute the data for use in more than one unit at the same time, you will
not only have a contractual issue, I suspect the FAA would be inclined to
withdraw the IFR certification of the installation (s).
