My Insight had this installed when I purchased it. It uses a Peripheral interface, and also has RCA inputs for an axillary input. It works great, I just don't use CDs anymore, and I replaced the radio with a media center. I'll let the changer with interface go for $100+shipping.
I also have the original Insight radio as well. I would sell it for $50+shipping.
