Thanks. I'll try it. The first screenshot shows PHLI Lihue, Kuaui, Hawaii. The airport is slightly out in the water but it's pretty close. I call this 'normal'. The second is PHNL Honolulu, Hawaii. The destination is PHOG Maui but notice the GPS waypoints are no where near their correct land mass positions. The range circle agrees with the landmasses but the GPS plot appears to be on a different scale. The only solution I've found is to shut down X-Plane and re-boot.
