The Installation instructions say, "Copy the *.img into the folder /Garmin/ of your microSD card. Installation in the onboard memory is not recommended."

Have you installed these maps successfully in a Fenix 6?

I downloaded the map but i only havé garmin contours but i dont know if it will work

Yes, no issue. The recommendation originates from old GPS devices with limited storage.

You need the main map as well. Contours are only the contour lines of the elevation models, no roads or paths. 

I know but I dont have the original

the main map I thune there is a problem on the site for Asia all the map are 5,9ko 

Oh, you are right. Another free alternative: https://garmin.bbbike.org/

Or another, not free one:

You could also check in Garmin Express for official Garmin maps. This will be the most expensive option. 

Thanks on bbike which format do i have to choose? Garmin osm latin1,osm UTF8 ,ontrail etc?

I don't have a recommendation. It's different styles and different character encodings. You need to try and see if they work for you and if you like the map style.

Yes i see that I dowloaded several i Hope it will works but the only way I know that is when I will be on Korea
