Ya... Sirius is Seriously out of whack. Mine had an XM setup preinstalled and im quite happy with the installation. The XM antenna is kind of unslightly and big but its very well installed and the receiver module control is attached to my dashboard in a thin inconspicuous location to the right of the steering wheel... very cool. XM is much better and also much more financially stable than Sirius, which is teetering on the edge of extinction since this is the kind of market where there really can be only one market leader, and XM has most of it.
Also on a side note, I wonder exactly which CD Changer option they would need the splitter for? Most if not all OEM BMW changers are hardwired on a special Changer BUS, the only way a splitter would be needed is if the car has had one of those crappy FM modulated changers added.
