In the default Carenado MFD we get to see the Flight Plan with magenta lines when its programmed with the stock FMS.

 

In the modifications with ISG FMS and/or the modification with GTN750 is there a way to see the flight plan in the Carenado MFD or the GTN750 map display ?

 

For the Carenado MFD under ISG FMS integration the only way to do it would be loading the flightplan from FSX planner (which off course excludes SIDs, STARs and Approaches ?

If yes, for the GTN750 would the same work or would it need other way to import/program it ?

I use the GTN750 and manually load the flight plan. Only takes a minute or two. I don't believe the functionality to automatically load the flight plan into the GTN750 is available. The MFD shows whatever is programmed in the FMS either manually or loading in the "ATC" Flight Plan which is the FS X flight plan.
