you get to access all the playlists etc through the touch screen, only annoying bits are, it defaults to the main selction list so you have to drill back in and search, really easy to use, the connector charges the ipod, not all ipods work nano v4 does, its slow shuffling between songs, you can use a small hard disk which i'm told perform slightly betterand not as attractive to theives
since i got a nano i dont have any cds in the car unless of i have bougt it as you get titles and artist in the display and if MFD is on audio can scroll through tracks and see details between the dials
