personally i still use AUX sometimes but i mainly just use USB these days WAY better sounding and 32 gig usb drives are like 15 bucks these days. and i dotn have to worry about keeping anything charged or an annoying cord (bluetooth is okay but its worse than AUX) only downside is you kind of need a Double Dinn unit or a ton of music on a USB drive can be VERY annoying
