So the other day I hear an add while listening to my Sirius in my car, to call and get the "best of XM" on my Sirius radio. The gist of this is that Sirius simulcasts the popular XM channels onto unused Sirius channels (i.e. XM channel 202=Sirius 197). Of course, channel 197 doesn't exist in my idrive, so I call to upgrade. I am told that all factory car radios are incapable of receiving the new channels for some reason. What is really annoying is that my vehicles that have XM can receive the new Sirius channels w/o incident. Is BMW working on a new satellite radio receiver seeing as how the two companies merged?
