I just traded in my '04 Sport and the dealer would not give me anything extra for my system, so I decided to pull it out and sell it separately. It is an Alpine IVA-W200, NVE-N871A Navigation unit, Sirius data/audio tuner and steering wheel controller module. This unit is a perfect fit for the 4th gen. I would be willing to sell them together or separate. Let me know if you are interested.
