Ron,
I checked the Jeppesen database which came with my Airmap 1000 and
it was 10.3mb with the date being March 17, 04. The current database
is just slightly larger 10.4mb (or something like that).
I'm not sure whether your Airmap 100 uses the same database. Just
want to let you know that there is not much difference in sizes between
04 and 05 data.
