I am not sure I have a problem with this unit that I purchased today and installed in the A2A Cessna 172 in P3D.  Everything works so far except when I take a trip from one airport to another, as I am approaching the destination airport, and I look at the page that has the airport frequencies that were there in the  departure airport, they are still listed as well as the departure airport name . I watched a video on the 430 by Garmin on Youtube, and the instructor said that once you leave the departure and start for the destination airport, the frequencies are supposed to up date to show the destination Airport name and the ATIS, Tower, Approach, etc.  but this never happens. Is there something that is not right with my installation, or does the Mindstar unit not have this function? 

The documentation we used for development does not list this as the behavior the unit has.  I'll add it to a list for looking into.
