If anyone have a 2011 Uconnect (System updated 2015), and you have some trouble for big library, this information can help you. I spent so much time to find the best and the easy way to synchronize my iTunes library (70 GB / 8000 song) First SDXC (Fat32) don't work in my 2011 Journey, only SDHC (Fat32), so I'm limited to 32gb cards. I decide to use a 128gb (Fat32) USB stick and it work great. The first try, my system recognize only 5999 songs, after a lot of recherche I've found the problem. Uconnect is enable to read only 1024 folders, and my song are organized by Artist/Album/Songs. I need to eliminate some folders and organize my usb stick only by Artist/Songs. After that, I can see all my 8000 songs. For do that : On Mac OS, I've use the 5$ application M3Unify from DougScripts. (http://dougscripts.com/itunes/itinfo/m3unify.php) This application can synchronize all songs, and playlist on your USB stick / SD Card. For the playlists, you need to export 1 playlist at a time. (By drag and drop in the application) With this application you can export songs by creating only artist or album folder if you want, so this is reduce the number of folders. On windows, I think Media Monkey can do the samething. After a synchronization on the stick, Uconnect system need approximately 15min for enable navigation by Artist / Playlist / Albums... Unfortunately my 2011 Uconnect don't allow me to see Artwork, even if all artworks are embedded in each song. Sorry for my bad english !
