Convert Sirius to Ipod?
 

Is there a way to convert the Sirius radio dock to an Ipod dock? I just purchased a 2007 Mazda 6 Wagon with a 6-cd changer. Yay! It came with a Sirius radio setup, but I don't want it. Instead, I'd like to use an Ipod. Is there a workaround, or do I have to remove the Sirius radio and add an Ipod dock from Grom, XCarLink, or someone?

Thanks for your help. :p
