I found that the best way to copy music onto an SD card that my Zumo 590 could see (format) was to;
1. Put the blank SD card into the Zumo
2. Plug the Zumo into the computer and then drag the music to the SD card in the zumo via the file directories on your computer.
It should ask if you want them converted. Click 'yes to all' and sit back.
This was how I finally got them all working perfectly on mine.
Good luck.
