How do I get the approaches selections when after a highlited airport shows none?  For example when I fly to Olympia Wash. and hit the Porc.  Button and then select by enter the  approach, then all I get is a widow with Olympia at the top but no types of approaches, and I know that it has ILS at runaway 17 which I have flown many times before in other Micosoft Flight Simualtors with Charts from Jeppsen.

I have looked in the manual of GPS 500 but can't seem to figure this out and help here?
