The Head unit is a Pioneer 8400. I have the same model. It has dual faceplates, as the front slides down to show a second display. It does have the ability to use AUX inputs.

Great Head unit, plays MP3's and WMA's. The MP3's can be sorted into a max of 8 file folders, so you can easily store a varity on you disk without having to look for a song.

BTW... where did you get the panavise???
