It's a CDX-565MXRF Sony XPlod 10 disc changer. Works great I have original packaging and everything. I only used it for like 2 weeks before I wrecked my other car. (It still works great after the wreck, nothing near the trunk was hit). I would install it in this one but I need $ and would rather sell it than pay to have it installed again. It has the advanced esp, bass boost, wireless controller and the wired controller that goes on your dash. I was thinking $130 for it.
