I just replaced this like new Alpine head unit with a Pioneer AVIC-N1, so I don't need this anymore. It is cosmetically, and mechanically like new. It includes the manual, remote (with fresh batteries

), and everything as shown below in the pictures. Here are some of the specs for it:
Alpine CDA-7894

MP3 Player Features
Headunit Type MP3 Player

CD-R Support Yes
CD-RW Support Yes
CD Text Yes
Disc Naming Yes
CD Changer Support Yes
Oversampling 8 X
It XM ready also, for those that want to plug in an XM receiver and listen to COMMERCIAL FREE FM radio.
It plays MP3's too(some of the specs are listed above), so you can burn a disc with a bunch of your favorite driving tunes and listen for hours and hours without needing a CD changer (but a changer will plug right into it if you want one).
It has a C5/Z06 mouting kit with it.
That's just touching the surface of what this unit does. It was $450 new, but I'm asking $200 shipped in the lower 48 states.
