Apple teamed up with SoundGate on this product. I contacted SoudGate's tech support with some questions. Here's their reply:

"With the iCruze you will have to lose your factory changer, and would not be able to get sat. radio either, but you will get to control your iPod from the factory radio. The countdown on the Monster Cable website does reflect release in 12 days. Keep watching it though, they have changed the countdown a couple of times. Monster Cable is doing the distribution of that piece, it will not be available through our dealers unless they are also a Monster Cable dealer."

I am still unclear as to whether it will work with my BMW's OEM system w/ DSP. (The iPod kit from BMW isn't available for my car. Nice.) I'm anxiously awaiting more detailed specs. What a riot that they missed the Christmas shopping season! Whoops.
