I got Sirius satellite radio now!

What does an FM Modulator do? I got my setup for free so I dunno

It basically adds a cd player, satalite radio, or whatever thru your FM cord on the back of the radio. Then you just tune in to a specific FM station, then you get whatever parepheral that you hooked up..and keep your stock setup. Its probably the only way to get satalite radio unless you have a pioneer or kenwood XM or Serius deck.

I like to think that the difference between the two is price. There is alot more than that but then I would have to basically write a book. for 12.95 a month you get sirius for 9.95 you get xm. I have sirius and like it better. its more in tune to listening to music.
