"New wave of radio choices: Satellite or HD?" LA Times
"But for many potential buyers, the choice of XM versus Sirius won't be made in an electronics shop or online. It won't even be based on which service might be preferable. More and more, when people buy a car it will come with satellite radio, Kidd said. Within two years, according to announcements made by car manufacturers, 30% to 50% of new autos on lots will have the radios installed. The major automakers all have deals with the satellite services. Honda Motor Co. and General Motors Corp., for example, have exclusives with XM. Toyota Motor Corp. and Ford Motor Co. install only Sirius. The decision will be simple, Kidd said. People will take what comes with the car."
