Power inRoads for a Fathomoter survey in New York?

I'm trying to learn Power inRoads for a fathomoter survey in New York. All of our reference files are in Power inRoads and we're having trouble finding reference materials. Does anyone know of good sources specifically for Power inRoads? I've found a lot for OpenRoads or regular InRoads, but they're built on top of microstation etc. and not AutoCAD. 

If anyone could spend some time teaching me about how to use it, that would be great and very welcome. 

Connect Advisor does not work with inRoads and I could not find any specific LearnServer videos dedicated to it.
