Can bus

From my simple mind, I wonder if XM and Sirius CAN BUS data is compatible.

My factory HU has an XM set top box located in the trunk (with its free 90 days running out) but I would prefer to add another Sirius radio account and replace that component with a Sirius SDARS set top box.

My other option is to splice into the input of the head unit (pins 4 and 20 on my cable) and feed the output from my trusty PNP unit onto those connections and replace the covered antenna with a Sirius one?
