Another big question is: Are the two systems compatible? For right now, the answer is no. Sirius can only receive broadcasts from Sirius satellites, and XM can only receive broadcasts from XM satellites. Several years ago, the FCC ordered both companies to develop a receiver that could receive both services. Although the two companies say they are actively developing the technology to do so, there is no word yet as to when it might be available to consumers.
