In addition, this project will give us an excellent opportunity to integrate our innovative radio service with the cutting-edge products and services offered by some of our high-tech partners."

In addition, XM Radio has entered into a 12-year distribution agreement with General Motors to integrate XM-Ready radios into its vehicles commencing in 2001.
