I've had Sirius Radio since it started, and paid a one time fee of $499--and never have no payments. A lifetime subscription. But it's currently on a "Sportster" radio head unit.
I wonder if Sirius makes a portable radio unit, that would operate thru the USB port on to the Camaro's radio?
I'm not gonna install another antenna just to get Sirius in the car. While I haven't looked in to it lately, it used to be that I could transfer my lifetime subscription to another Sirius radio.
