I have a direct sirius tuner box. Its currently connected to my KDC model head unit, i dont know what other models it supports. Connects to the headunit with an IP cable (think thats what its called) just like a cd changer. Also has a pass thru on the unit so that you can still use a cd changer at the same time. Only thing it doesnt come with is the antenna, mine broke when my buddy pulled on the wire.

I dont have sirius anymore, havent for months, so i have no use for it.

I paid $95 for it last year, and im asking $45 OBO for it.

 

So you can use your sirius ready headunit for sirius instead of the extra unit. Just like changing from fm to cd, u change to sirius
