On the net early this morning I came across these...
For those who use the stock navdata in FSX an P3D , here is something that may interest you.
fs aerodata is a service that will update your stock navigational data in FSX, which until recently has been a
time consuming if not impossible task.
You will need a subscription to Navigraph, as that is where they get their info along with a subscription for fsaerodata's service.
This could be nice for those who use the GPS alot. now you can use your charts with FSX.

Navdata.
