Interesting. The points are clearly marked Left Channel, Right Channel and Aux Ground (which would be the common between left and right).

Question though, how does the input work in practice? How does the H/U know to use the signals you are inputting via the 3.5mm plug, versus some other function (FM/AM, CD), etc? What do you have to do to the H/U to get it to accept this input? I ask because the points you used are clearly for an Aux. In, yet others have reported needing to use a blank CD and this new signal rides on top of the blank CD (i.e., the H/U thinks it's playing a CD). But it this IS a true Aux. In, how does the H/U recognize it? (BTW - I have the same H/U in my '03, which is why I'm asking!)

Thanks,
