I have both a Macbook and a Windows PC, it appears the only way to upload music is via the Garmin Express app.
For windows it takes almost 5 minutes for it to load the screen to allow me to crossload the music, when I choose Album it doesnt show albums it shows individual songs so I have to select them one by one.
When using the Macbook it only allows me to crossload music from ITunes, I have lots of music downloaded as MP3 from Amazon etc and therefore cannot crossload from my Macbook.
I managed to get 2 albums across to my watch with half the memory used, of course with the limited memory on the watch and high quality audio files theres no way you will get 500 songs on, why therefore doesnt the Garmin Express app offer the ability to reduce quality size to increase the number of songs that can be uploaded?
Is there a better and more user friendly way of crossloading music to my 645M?
All of these items are basic, I've had iPod's and Sony Walkmans from about 15 years ago that had better content management capability why in 2019 is this such a difficult thing to do on this device?
