Crossed wires: What's the best aux input?

Hi folks,
I recently bought a 2001 330i sedan with Business CD, Harman/Kardon, and no CD changer. There is no "mode" button on the receiver face. There is also a badge in the trunk saying the car is pre-wired for a BMW phone (I have no idea how common this is). After calling the dealership and conducting what I thought to be thorough research, I purchased the USA-SPEC PA12-BMW-DSP, on the assumption that the HK "HiFi" button on the center console indicated the car has DSP.

When I went to install it, I found that the cables provided did not match up with what I found in the trunk of my car, or anything that I'd seen in an installation video. For one thing, the three-pin (white-brown-red) connector had the brown wire in the second position. And the second set of connectors (on the adapter) did not match any of the three other connections present in the trunk of the car. See attached pic of the wires present in the trunk.

What I'm seeking is a hard-wired solution for my iPhone. Having it charge from the same connection would be nice, as would integrated controls, but neither is a must-have. Whether the audio signal travels over Apple dock connector or 3.5mm audio cable doesn't really matter either, but I can't live with an FM modulator.

With this post I hope that someone here can make a recommendation about what solutions will work with this setup, or at least tell me:

Does the HK stereo in the '01 E46's indicate that DSP is present?
Will the Audiovox/DICE Duo/MediaBridge work? If so, do I need the DSP adapter?
How do those devices differ from the Soundplicity kit?

Thanks very much in advance!
