I got a used Sirrus radio for my car from a co-worker and decieded to give it a show. I have been with XM for 3 years, and it was losing its luster. So, far the doggie company sounds good in my car. With XM on my 40 mile drive to work i would get over 5 drop outs, with Sirrus, i didnt receive a one. I also liked listening to Radio 1 in the morning. My wife still has her XM in her car and she likes it so we are going to keep it, but my MIFI is now going to be put on the back burner for a while.
