This is a used Alpine PXA-H800 System Integration Audio Processor. Used for custom car audio installations to interact with factory and aftermarket systems. 

All components are in good condition with scuffs, marks, scratches and wear from normal installation, use and removal. All pictures are of the actual item for sale. I do not have any gear to test the unit with, but it was power tested and properly detected by a computer so I know the unit powers on and is able to communicate with a PC with no issues.

It comes with some installation cables and accessories. It does NOT come with the Remote Commander unit (it's an optional remote/display for the unit).  I am not sure if the set is factory complete, everything included is listed below and pictured.
