GARMIN ASSISTANCE

Hello everyone. This one is a reach but I thought I would give it a try.
I have a Garmin ETrex 30. It saves waypoints in a .gdx format.
My older Garmin, and the software that accompanied it, has mapping software for my laptop that saves and displays way points in a .gdb format.
The mapping software that came with the old GPS is called MapSource.
QUESTION: does anyone know how to display the .gdx waypoints on the MapSource software?
I have sent this to Garmin as well
