I ordered a dice duo silverline trunk interface a few days ago, and just waiting for it to arrive friday

I've seen a few videos and it looks like all I have to do is lift the center console, find the two cd changer wires, connect the dice unit and stash it under the console, route the ipod cable through the console, and that's it? Does it really involve the trunk at all? I saw the Bavarian Sound Werks instructional videos and that's all they showed for the x3...

Any advice for an x3 dice install?
