Is there a dual feed system now? Or are they broadcasting the same programming on both formats?
I don't know what you mean by dual feed system, but it is now called Sirius-XM radio. That is what they say when they identify the stations and I think that comes up on my display. It appears they have merged the two systems together and have kept some DJs from both systems. I have it in my car so I don't know about off the shelf, but you could try calling XM (or Sirius-XM) as they sometimes have special deals when you call. Or they can tell you what retailer to go to.
