Ford has decided to stay in bed with Sirius for three more years than originally planned. The deal between Ford and Sirius, the satelitte radio company, was supposed to end in 2008, but it has been extended until 2011. The deal is an agreement that Ford will only offer Sirius satelitte radio systems as options in its cars, not XM, Sirius' main competitor. Sirius believes that over 90 percent of Ford vehicles should have Sirius available by 2008. The agreement does allow Ford to become non-exclusive in 2009, but it also allows an extension through 2013. While Ford and Chrysler offer Sirius, GM and Toyota have deals with XM radio. It is too bad that more choices aren't offered, but this is how the fledgling satelittle radio industry chooses to promote itself.
