can't read img from memory stick or SD card

Hi SUSSAMB ,

I've read you saying that Basecamp can directly read a map (.img) from a memory stick or SD card but this is not working for me.
The img file was creating using IMGFROMGPX and I'm able to see it in my Fenix 5x but not at Basecamp.
Any clue?

Thank you,

PS: I tried to upload the img file bit for some reason the forum doesn't allow me to upload any kind. Always gives me a message "invalid file"
