Heh, I really have no clue what I'm talking about.
You have to double connect the blue/white wire wherever you connected the solid blue wire. In other words, connect the blue wire and blue/white wire to the same spot (wherever that is, I forget). The amp turn on gives power to the audio (I believe?) and it also controls the antenna assuming you have a non-stationary antenna.
EDIT
I went ahead and took a look at mine. I have no clue what I'm talking about
Connect the blue wire to the blue/white. Here's a picture. The blue/white is the one on the bottom right.
