I used the music in the FR945 without issue, downloading mp3 files with Garmin Express. Since yesterday with Garmin Express v. 6.19.2.0 and the new firmware 3.30 I erased the old songs and I transferred to the watch some new songs. Garmin Express says it's all ok.
If I enter in the Garmin folders, I can see the new songs, they are on the watch. But when I try to play music, on the watch the old titles appear (of the songs that are no more on the watch) and I can't hear no music. Ideas? I tried to hard reset the watch, but it didn't help.
