Hey PropellerHead, did you ever resolve your issue with where to locate your IBUS adapter? I'm in the same boat that you were, and have been having issues with finding where to tap into the IBUS connection without having to extend the IBUS wire all the way back to the trunk from the head unit as Resler suggests is the only good way to do it. I'm currently tapped into the LCM, but have been experiencing issues with it tapped there as well, so I'm trying to weed out offending IBUS devices that aren't communicating correctly.
