My (US) 2013 S4 came with blue grommet iPod cable which I exchanged for red grommet iPod cable at the dealer (they made me pay the difference though). I did not know that the red version keeps the signal digital which is good. Red also enables album artwork and video playback, but iPod as source does not give you browse by album cover, and the video stays in 4:3 format, so widescreen videos have black bars on top, bottom, and both sides. Jukebox has album cover browsing, but no real playlists. iPod has playlists. You can make playlists for SD card but not as easily as setting up your iPod.
