As the exclusive satellite radio service for Infiniti, XM will be a standard factory-installed feature on every 2008 Infiniti model, including the G, M, FX and QX.

“Becoming a standard, factory-installed feature for all 2008 Infiniti models is an important milestone for XM,” said Steve Cook, executive vice president, Automotive, XM Satellite Radio. “Infiniti customers will find XM is a perfect complement to the Infiniti driver’s experience.”

Additionally, XM NavTraffic, XM’s real-time traffic service, is available in the 2007 Infiniti G35 sport sedan and is a standard, factory-installed feature on the 2008 Infiniti QX full size SUV. Infiniti will expand XM NavTraffic availability in the 2008 model year. The 2008 G37 Coupe will make XM NavTraffic available as part of the vehicle’s navigation service, and will feature standard XM Radio.

Now available in 50 major U.S. markets, XM NavTraffic delivers alerts regarding accidents, road closings and traffic. Where available, XM NavTraffic also provides information that allows users to view an overlay of color-coded traffic flow information, indicating the average speed of travel along the driver’s planned route.
