I am almost too embarrassed to ask but here it is:

I currently have a lifetime subscription and use the SC-C1 tuner in combination with a Sony interface (SNYSC1) to listen to Sirius on an aftermarket car stereo. I am considering the purchase of a Pioneer radio (AVH 8400BH).

If I want to listen to Sirius on the new radio, I need not contact SiriusXm and modify my subscription, correct? It would be a simple matter of replacing the SNYSC1 with a bus interface that is compatible with the new pioneer radio (CD-SB10), right?
