Yeah, Intravee claims they have proto code that will control an Alpine XM tuner, and provide all the great data that they do with NAV and the Ipod. I already bought the Alpine box, and I am waiting for the code update to try it. Right now its buggy and they won't release it. Soon, very soon!

I have multiple family members with XM, so we get the volume discount. My car was pre the Sirius wiring days, and I like the Intrvee interface, so I will happily wait until they ship v6, and hope it supports XM.
