I'm in the same boat and like my Sirius too. I don't have an iPhone either, but the wife does and I'm sure she would like the connectivity. Since no way to connect Sirius, probably going to go with NA version, but now the question is NBT over CIC really worth it?

I'm in process of retrofitting NBT to an E38 and there aren't the coding nightmares to get it to work, like there is with the E70. So instead of having to learn all there is about coding, kind of looking for a kit. I've seen a lot of good CIC kits and talking with some suppliers, there is a lot more to adding an NBT to an E70 vs. a CIC.

Watching this retrofit to see which route to go.
