General Motors Produces Three Millionth Vehicle With Factory-Installed Xm Satellite Radio

Washington D.C., September 22, 2005 -- General Motors announced it has produced more than three million vehicles with factory-installed XM satellite radios.

XM is the exclusive satellite radio partner of GM, which offers more than 50 vehicle models that feature XM Satellite Radio. In model-year 2006, nearly 90 percent of GM’s U.S. retail models will offer factory-installed XM satellite radios as either an option or as standard equipment.

GM was the world’s first automaker to offer satellite radio and remains the industry leader in offering factory-installed satellite radio to its customers. GM began offering XM Satellite Radio in select Cadillac models in November 2001, the same month that XM launched its service nationwide.

“We’ve made XM Satellite Radio available across the breadth of GM’s U.S. portfolio because our customers tell us they highly value the superior-quality programming it provides,” said Mark LaNeve, GM North America Vice President Vehicle Sales, Service and Marketing.

“This is the latest milestone in an extraordinary partnership between GM and XM,” said Hugh Panero, President and CEO of XM Satellite Radio. “Being the exclusive satellite radio partner of the world’s largest automaker has been a key element of XM’s success to date. We look forward to even greater success as GM continues to offer XM across its vast model line-up.”
