1) An error ocurred during the sync. with garmin connect.
I'm on Garmin express, I don't understand why it speaks about garmin connect
So I cannot sync my Montana, and so I cannot sync. the waypoints I did on garmin explore
2) I'm unable to see the map I booked (neighter with the montana, neighter the one I booked online and install on SD card) on garmin express
It's not more in "Stockage amovible"
For now I don't recommand to buy this GPS, not intuitive, to be use with lots of apps, all linked, also not intuitives ... I was expecting something else for 700 €
