Therefore I did not investigate the "save" function at all and just assumed it was not possible. For me the ability to save a Skydemon Flightplan to a card is just fine and whosever PC one is using this will be OK.
Re Garmin, its probably a bit more complicated but if you have a laptop but no means of web-enabling it, then that wd be fine too.
Again my apologies for not investigating properly.
