Duplicate your nav.dat first and then edit the original file (safety first).
Open the file using a text editor and search for the line:

I used data from the "Deutsche Flugsicherung" and checked it in google earth, so the new positions should be correct.
If you´re not sure what to do - download Robins update!
Happy landings!
