The Tech writes a useful review on Tao XM2Go Receiver and XM Satellite Radio. It recommends:

I really enjoyed playing with the Tao XM receiver, and was quite impressed with XM’s radio service. If you spend a significant amount of time in your car, you will be blown away by how much local radio bandwidth is wasted on crappy advertisements. The Tao receiver actually comes with a car and home kit, along with headphones and a random assortment of other stuff to let you do everything you want, right out of the box.
