Actually, the "car dock" SIR-CK2 comes with the mini-jack to RCA patch cord to connect directly, and also FM Modulates, wirelessly (unlike my kenwood in the H2 that hooked up inline w/the antenna). You could, I guess buy a mini-jack to cassete adapter use it. So far I'm impressed with the wireless FM Mod. The Actual tuner unit has a menu item to enable or disable FM modulation. Here are the actual product #'s and a link to the crutchfield site.

I like Sirius over XM, mainly because it is 100% commercial free. Also it offers NPR (I'm a car talk fan).
On a side note: My stereo guy here said that Alpine (others to follow) will offer tuners with XM or Sirius capablilities built in. I'm going to wait on my stereo replacement until some of the '04 stuff hits the shelves.
