Some carmakers giving customers a choice between Sirius and XM

Subaru said recently that it's considering letting customers choose either
Sirius or
XM satellite radio service with their new vehicle, something that Toyota, Nissan and Audi already do.  Most other carmakers, however, have taken sides, with Ford, DaimlerChrysler and BMW in the Sirius camp and General Motors, Honda and Hyundai on XM's side.  But it looks like you're still out of luck if you want both Sirius and XM radio in your car— unless those
merger rumors pop up again, that is.
