Jimski none of the World war two Simulator have a good navigation display. Thats one element that has been missing.

Have you tried this program :http://www.cfsops.com/Modules/cfo_weather/Cfo_Weather_75.htm

It has a Navigation display. You can also change the Weather while flying. Granted you have to do it manually.

Try it and see if you like it.
