If any one has a Pioneer unit, they are coming out with a iPOD adapter for it. It supposed to be release this month, and be backward compatabile with older radios, plus have some of the same features as the Alpine with some of this years models (ie. controlling the iPOD and getting the song/artist information displayed on the radio).

I haven't seen one yet, but am eagerly looking for it. The model number is CD-IB100
