XM/Sirus Antenna ?

I currently have the car kit for the Delphi Sky Fy II (XM), and I want to get Sirius.  Can anyone tell me if the power supply and antennas are interchangeable, in other words are the cable connections the same?  Does the satellite signal come from the reciever itself or does it involve the antenna as well?  I am basically looking to be lazy and just swap the reciever versus the whole kit.

no. your gonna have to swap all of that stuff out. only the xm unit will work with the xm units and vice versa. sirius takes 12v input, while xm take 5v and 6v inputs. the antenna's are also different plugs. bottom line, your gonna have to do a little work on this one.

Thanks for the info.
