Came with the car I purchased.  The unit powers up and was purchased and installed shortly before I purchased the car.  I'm only selling because I decided to go a different route with my setup.  The unit has a few minor surface scuffs as seen in the photos.  Below is the list of features from the Dedenbear website.
