I got Sirius added as an option on my new Infiniti. I could have gone with either XM or Sirius but chose Sirius because it had a better lineup of Talk Radio.
It's great, especially if you do a lot of driving and like talk radio -- no more searching to find a station as you travel through the rural areas!
on national talk shows, like Rush for example, what happens when they take a commercial break? Are there commercials or is it dead air?
