Hi.
Still looking to buy this watch and have a question about iTunes and transferring music to the 645M.
1. All my iTunes music appears in Finder on my Mac with file extension .m4a. Can i load this onto the watch via Garmin Express (or other)? Or do i have to convert everything to .mp3.
2. If i sign up to Apple Music and sync some albums to iTunes on my Mac, what extension will they have and will the files be transferable as well?
I know there is a generic streaming answer that is "only iHeartRadio and Deezer". But for files stored on my computer (obtained via a subscription service or purchased), how does this work? Are some given an incompatible extension and hence aren't available for transfer ...?
Thanks.
