Importing Flightplans from Flitestar into the GNS400/500
The fpl format is XML.
The Garmin export/import mechanism also allows the export of user defined waypoints for inclusion in a flightplan which can ve very handy.
The main gotcha with the fpl format is that the GNS at least, can only accept waypoints with a maximum of 5 characters in the name. Flitestar allows waypoint names of any length, so you need to be careful, otherwise you will just get a cryptic "not a valid flightplan" error from the Garmin importer when trying to import the flightplan.
I regularly import from Jepessen Flitestar into the Garmin GNS400/500.
I have step by step notes of how it can be done for the GNS. I am assuming it must be almost identical for the G1000.
If you want copy, I have them in pdf format. Feel free to PM
