I want to extract the lat/long for route waypoints so I can put them into Garmin GNS 430. Am I missing a method to get a lat/long?  If I put a waypoint at some random point then the lay/long is shown in the properties but if waypoint snaps to a town it just shows the name when you ask for its properties.

If you're looking for the coordinates for the waypoints in your planned route, the simplest option is to turn on the 'Show Position' column in the PLOG, which will give you a column containing all of the lat/longs.
