Have had Sirius for about a year now and really like the programming. I have had a problem though, and it may end up making me leave Sirius. I have one head that I like to swap from car to car to home. I started having trouble getting the antenna plugged into the head unit at home until I finally couldn't get it to work. I went to Radio Shack, and they told me Sirius doesn't make that setup any more, and I would have to get a new head and antenna.
I was able to find the antenna on line at Sirius, but now the antenna in one of my cars won't plug into the head unit. Is this common ? Is the XM hardware any more user friendly ?
