However, using any one of many on-line sources for generating
airport/navaid/obstruction waypoints, and other software to upload these
to
the unit, I now have a very nice unit. It shows all of the airports
within
a 200 mile radius (indicated by an airplane symbol,) all of the VOR's,
and
all of the towers 1,000' AGL (indicated by a tower symbol.) The unit
is
limited to 500 of these user-defined waypoints, but if I decide to take
a
longer trip, I can easily go to a website and generate waypoints for the
route and upload these instead of the 200 mile radius ones.

which website do you use? Do you happen to have a list of
websites that offer these waypoints?

I've used these to get data from:
http://www.airnav.com/ for airports and NavAids and
http://wireless2.fcc.gov/UlsApp/AsrS...tionSearch.jsp for
antennas and towers.
I put the data into spreadsheets, export it to my GPS mapping software then
download it to the GPS. Works fairly well.

There are aviation databases available for download which are quite large. I
remember downloading a database once and deleting all the waypoints that
were above or below certain latitudes and longitudes to get the list down to
the state/area that I would do +95% of my flying.
