Like you all, I am disappointed on Honda's handling of this; not only the "XM ready" debacle but also the incredible cost and machination to install the XM receiver.
I am an exisitng XM customer and my XM2GO works fine with both the the FM modulator and the AUX input on my HCH. If I didn't already have this hardware I certainly would opt for the new Pioneer Inno vs: having the Honda XM install. The factory install would be nice tobe sure, but the Inno has the same XM features and also allows 50 hours of XM recording and your own mp3's. It's a nice, small, personal music solution at less than half the cost of the Honda install and it can be used in other vehicles and the home as well.
