I like Sirus because Pittsburgh radio sucks. When it comes time to renew it, the car saleman told me when they call just say that you are dropping it. each time they call they will lower the price. It takes a little work but you can drop the price to 25 dollars for 6 months.
Thanks for the info - I had a test run of 3 months when I bought my car and let it expire. The CD player comes in handy on long trips - can fit a lot of tunes on 5 CDs of mp3s.
