More carmakers now offering both Sirius, XM
Rather than pick sides in the battle between satellite radio services, some automakers are waving the white flag. Subaru said last week that once it begins offering satellite radio, it might join Audi and Nissan in letting customers choose either Sirius or XM, the two satellite radio services.

Thats a good idea, this would force both companies to offer something that people wanted more. Competition would be good for us consumers when neither company can assume that a car purchase is a sale for them. They will still have to fight for our business and that is good for us.
