I've got an Alpine CDA-7893 with the PAC converter for the Bose system and the ON-STAR system adapter already wired up, so this unit would be plug-n-play. It also has the mounting bracket/system already attatched.
Unit came out of a 2002 Tahoe (with bose and onstar) and works great!
Remote control, box, faceplate case all included.
I also have the Alpine Ai-NET XM radio controller included. I DO NOT HAVE ANY WIRING HARNESSES OR XM ANTENNA, only the "box"/controller.
Unit was only used for 1 year!
$300.00 + shipping for everything. I have plenty of pics so if you have questions pm me.. Price is not negotiable(sp?)!
