The 645 MUSIC Effing sucks! Airpods won't work. With other headphones, the 645's Bluetooth is so weak that it actually matters what wrist you wear the watch on? I mean come on! Junk.
I have many playlists in my iTunes (on my MacBook Pro) but on the Garmin Express app they do not appear. I am trying to put the music on my Vivoactive3 watch but nothing happens. Is there a way? I have these random playlists that are from Spotify but I have no idea how they got on my watch! Strange......
