Hey,
it took me a while to figure this out, so maybe this info will help someone else? The garmin/Zuma, whatever you want to call it that came with my 2010 CVO Ultra has the ability to play music. First of all, it says you can only use a 4gb SD card and i am successfully using a 16GB card. I copied all my music from my music folder (itunes) and out of 1,600 songs, only 400 would play. Finally i figured out that the Garmin would only play MP3 files. I went online and downloaded a free program to convert MP4a files (itunes purchases) to MP3's. It took a couple hours, but i was able to convert all my music to my Garmin MP3 with the exception of the protected files. All in all, i went from 400 songs to 1,300 and it only took a couple hours to covert them. I almost said f%$# it at spent the money for the ipod connectivity, but i hated to do that because of the interaction of the garmin, bluetooth, and the head set capability. Anyway, i thought i would pass that along, maybe it will save someone else some frustration. Now i can give my buddies my SD card and they can copy it and enjoy the free music. Ha Ha Itunes!!
