Long Title kind of explains it.   Most of the basics are all working with the Standard Events...  However the Nav Frequencies are not able to be controlled externally and represented in the Sim UI.  I have created a workaround that will allow the External Radio Controllers to work.  What they display on them is the accurate Sim Data "Under the hood" but won't be represented in the RTU...  The VOR1 is tracking it and you will see this in the first few minutes of the video.
