When using Garmin Express I am trying to transfer files to the watch and just get an "Error sending files" message.
I have tried just copying the files to the music folder via windows explorer and it still does not copy.
File types are a mix of mp3 and m4a. Main music program is iTunes, but all files play in iTunes, Windows Media Player and Groove Music programs.
Any idea why they will not transfer to the watch?
Thanks in advance for any help.
