I seem to remember from the FSX version under the NAV/RAD menu you could enter a ILS freq, but not anymore with the P3D version. Manually tuning the ILS is not working also so I am stuck with changing the "config" file as you mentionned. Thanks very much for that.

That's not true, of course you can manually tune the ILS in the CS 757/767. It's done on the ILS tuning panel on the pedestal.
