Ah, now I see it. The smart antenna is needed for XM reception, (included)

It looks like a pretty interesting antenna, but one thing that I did
note: it has magnets in the base. If they're as strong as the GPS-10
magnets, they could create compass swing problems for folks. Not sure
how easy it will be to remove them, but it will likely void the warranty.
