OP: FSC code activation is all that is required. No need to complicate the issue further.
I've had both Sirius and XM in previous cars (Mazda RX8, Lexus IS350, Honda Accord) and none of them sound as bad as the BMW. If I'm going to nitpick one thing I don't like about BMW cars, the audio quality of the satellite radio is the probably it. Like I said, the satellite radio in my Infinti SUV sounds VERY good. On the flip side, the Bluetooth hands free system in my Infinti is terrible and the one in BMW is fantastic.
