"This is very exciting for SIRIUS, and marks the first of our 2005 model year factory launches with Chrysler Group," said Doug Wilsterman, Senior Vice President of OEM Automotive for SIRIUS. "We are extremely pleased to participate in Chrysler Group's 2005 model year product offensive, and we believe that customers will recognize Chrysler's $195 pricing of the SIRIUS option as an industry standard and compelling value proposition."

The Chrysler 300's striking new proportions combine classic American design and power with proven DaimlerChrysler technology. Marking the brand's return to a rear-wheel-drive, V-8 powered automobile for the first time in more than a decade, the Chrysler 300 pays homage, albeit in a very contemporary way, to the first "letter series" Chrysler 300s, which combined performance and prestige like no other vehicle at the time.

The Dodge Magnum is the new shape of American muscle, celebrating what American muscle cars were in the past, but with a design and packaging configuration that charges into the future. This category of vehicle offers the right formula of proportions, packaging, performance and appearance that set them far apart from the competition.

"The Chrysler Group is pleased to offer such a competitively priced entertainment package that will enhance our customers driving experience," said Jack Withrow, Director of Vehicle Entertainment and Communications for the Chrysler Group.

All Chrysler 300 and Dodge Magnum customers will be able to order SIRIUS as a factory-installed option for $195, including a one-year subscription with access to SIRIUS' over 60 commercial-free music channels and more than 50 news, sports, entertainment, traffic and weather channels. As an additional benefit offered exclusively to Chrysler customers, there is no activation fee to initiate the service after vehicle delivery.

Customers also may stream SIRIUS music programming over a high-speed internet connection at their homes or offices at no additional charge.

Consumers selecting the SIRIUS Satellite Radio option in their Chrysler 300 or Dodge Magnum will receive a small, mouse-like antenna mounted to the roof of the vehicle. Station selection with the radio is easy, using the same familiar method as selecting an AM or FM station. Consumers will be able to scan channels or select pre-set buttons for their favorite channels. Consumers will also be able to search both by music category and channel, which will be displayed on the radio screen.
