FLY is FUN

Hello
I have a Garmin fenix on which i recorded some flight
i used garmin basecamp software to convert the track in route and then export them in either gpx format or kml
in both case when i try to import via nav/route/import
it is said 0 import with no other information

i tried with an old gpx track from a trail i made a few years ago and it worked !!

So what is wrong with these new gpx file ?

Route and track are different. There asre impolssible to import track to routes, because track consists from a lot of fixes.

I will enable to import tracks to Logbook.

Thanks for your answer
does that mean that it is because there are too many point ?
If it is teh case how many do you support ?

With garmin basecamp software i converted track into route but with no specification as far as size or quantities of wp
and the result was not taken into account by flyisfun
same with kml converted with google earth, the result didn't work, is there a limitation there as well ?

There is no limitation - numbers of route WPTs.
Limitation is distance between two WPTs (Menu/App settings, Routes/Min dist. between 2 WPTs)
