I am trying to figure-out how to get the flight planning function to work on my AF-4500 system. I have been unable to load a flight plan from my GTN-650. It appears that the GTN-650 is communicating to the 4500 and when I looked at the GPS diagnostics everything appears to be working. However, despite loading a flight plan on the GTN-650 when you go to the flight plan in the 4500 it simple says "Flight Plan Unavailable".

I tried entering an internal flight plan, which I was able to do. However, when you hit the Activate nothing happens. Nor does the route appear on the map. I also tried to do a simple Direct To, after selecting a location, nothing happens...no line appears on the map.

I may be missing something really simple but I am stumped.
