It would have been easier to answer your question if you included more details. What stereo make and model installed in your dash? Any signs of a Sirius satellite antenna on roof, windshield, or dash? If you do a Google search of your stereo make and model you can find out if it's got Sirius built in (should be a choice on screen or buttons) or is just 'Sirius ready.' If it's Sirius ready, then you might look under the dash to see if it's been installed. You could also pull the unit out of the dash to see if it's hooked up. Most stereo units can be pulled from the dash in under a minute if you have the 'tools' to release it from the holder.
