garmin connect android app and gpsmap 64s

Hi everybody and thanks for this forum.

I've already tried to search related topic. For any mistake regarding this post, sorry in advance.

My GPSMAP 64s is connected to my Android smartphone Samsung Note4 via bluetooth: no problem, I can see android notifications on 64s display.

If instead i try to connect 64s to "garmin connect mobile app" installed into the same smartphone, I cant' find 64s item in GPSMAP list (only "276cx", "64" and "64sc" items are available).



I've tried to scan my 64s using "64" and "64sc" items. No way.

Trying to manually addict "64s" on garmin connect.com (following suggestion displayed into garmin connect app), I can't find any dedicated tool into website.

May you help me?

Thanks in advance.
