Bought these with my Eclipse AVN5510 head unit. They are universal to any/all aftermarket head unit and allow you retain your steering wheel controls. They are brand new , still in packaging, never been spliced or connected. New they are $125.00 I will include the websites install directions as well. Heres the link.

I'll take $15 off cause I dont need them. I already had one.
