I have an Ipod Classic 160 gig. with 500 + fill albums all organized with album art. (too many tracks to expect a USB stick to make finding anything easy, who knows how it works be organized) I'm OCD with my music! Anyway when the Ipod is connected via USB, the interface is awesome on the touch screen. I can browse, scroll by artist and album. It's really good and sounds awesome. If you use aux jack, like most systems you are constantly fiddling with input volume, regardless of the gain setting in the JL audio menu in U,-Connect. Classic.
