Sorry to highjack this thread.
No matter what I do, I only see message "PHONE CONNECTED?"
I do not know where the antenna goes. I dont even know if I have one.
As you did I disconnected that purple female plug it plugs straight in to my black port.
I also found a black plug that fits in to the blue port. I am at loss, I cant get this thing figured out.
See my pictures below...




Also see the black connector. I am not sure what that is. I thought it was the antenna.
