Use simbrief/Little NavMap both export flightplans created in the gfp format for importation into the GTN.

Occasionally, yes. You'll get a waypoint error in the GTN. I usually load the plan w/o the waypoint and then insert it manually. The GTN recognizes it that way but not in the import. Not really a big deal so far.
