I have 2 x brand new in boxes KCA-420i's. I got the last 5 of them at Alpine Canada. 2 friends & I got the first 3, I still 2 left. $100 + shipping. Combined with an Intravee, you get a pretty good interface for both iPod and Sirius (w/SIR_ALP1) on the BMW I-Bus. These are now discontinued by Alpine.
