Ah those sim makers... They think for us it's game, they don't know how professional we really are and how important simulation of real world is for us  ::)
Out of the topic, need to say, that "total overhaul" is a really good thing. I like improved cabin lightning and functionality of PDCS. It helps flight planning a lot and has some other useful features. Recommend to try if you didn't yet.
As for ILS DME and other navigational aids, I know that navigraph is supporting FS and a lot of other pay ware products. So their data manager can be used to update those. And if it really updates everything as it is per their charts, than it is really worth the money. Unfortunately they do not support P3D and CS 737 and it's sad. But I am thinking to move to MSFS in near future as I heard it is really good and navigraph supports that. Only waiting for pay ware aircraft to be available for that sim as there not much at the moment. And I really hope CS is also working hard on that and will catch up the market on time!  8-)
