Despite a lot of informational replies, I think this thread has gone away from the essense of what the original Poster has asked for, especially the navigraph/map suggestions, which whilst is a great suggestions is not a “replacement” for the map view from previous versions of FS, so i am going to try and answer this question, bringing in some of the answers already given above, into one “solution” 
Firstly, as already mentioned I think you accidently picked a COM freq, not the NAV/ILS freq.
Secondly, with regarding to the in flight MAP from previous versions, unfortunately that is no longer available with the same level of information in MSFS (which is why its called a VFR map now!), however, a very suitable replacement (and arguably better) is the afore mentioned Little Nav Map. This is a free thrid party application that can be run at the same time as MSFS. If you have a single monitor you can “ALT-TAB” to it, and if you have a second screen, you can display it on the second screen.
The reasons for suggesting LNM, within the context of the topic author question are the following:
- it can connect to the SIM and display your position on the map, as well as can display other AI/Real Life aircraft around you.
- It can load your existing scenery INCLUDING ADDON AIRPORTS. This is important if you have fictional add on airports, such as the closed MIEGS or Kai Tek. This will display any ILS/Taxiways/gates/Procedures as per what the SIM has, and therefore is closest to the old MAP from previous versions. Navigraph will not display any add on airports
- LNM can use different base maps (open streetmap, google maps, etc) and has other features that are extremely useful, but beyond the scope of this response.
NOTE: remember to import the scenery library form MSFS into LNM via the approriate menu on LNM on first install, and thereafter any world/sim update, or content update to keep it up to date with what is installed on the sim.
Navigraph as well as using charts is probably the most “professional” way of discovering an ILS, but is not a casual process and whilst good to learn, may be more than required for what the OT was asking. Also navigraph is NOT free.
