It means that with GPS input, the little airplane flys over the approach
plate that is displayed on the unit and it's actually in the correct
location. My FlightPrep/ChartCase program will do it on a notebook/laptop,
but it's windoze/hard drive based instead of solid state. Pretty cool and
dead on accurate when it works.

Now I understand. I have flown approaches with an MX-20, but having the
approach plate overlayed would be a definite advantage.
