I have an Alpine 6-Disc Ai-Net CD Changer for sale, it's in good condition. I believe it's the CHA-S614. I also have the metal frame or bracket for the factory changer with the cover that has the "S2000" logo on it. The Changer fits in the bracket and mounts in the trunk just like the Honda Changer. I have the Box and everything that came with it. Asking for $120 obo.

And I'm pretty sure it won't work with the stock head unit, someone correct me if I'm wrong.
