I thought the data files themselves were encrypted using the database
key per unit to stop the download from being copied.  Otherwise you
should theoretically be able to take a card from aircraft A and move
it to aircraft B and use it?  I've never tried this but I thought it
was not possible.

The KMD550 doesn't seem to have an internet-downloadable update, just
source-mailed card.

So, basically a using a SanDisk device, say their 8 in 1, one could
take a subscribed  Internet downloaded KLN94 update file and somehow
extract it to be popped directly onto the flash card instead of having
to either have an external docking station for the GPS  (not exactly
convenient at the tiedown), or spending however long it takes to
update the device via the cable using aircraft power, draining the
aircraft battery in the process?
