Well, I finally decided to call Garmin and see if they would tell me
anything. They would only say that the carts are proprietary and can't be
bought anywhere except from Jeppeson. I tried to engage the guy in a
conversation about the 530 upgrade, and he was not talking. Pretty
frustrating from a customer point of view.

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?
