el_duderino is correct, the connections are there. I am assuming that you don't have the CD changer, because if you do the reason you aren't finding them is because they are attached to it
. Keep looking, you'll find them.
Also, the Best Buy joker is wrong about the X5 audio system for U.S. spec vehicles. There's only two versions - DSP or non-DSP. Both have a separate amp in the back.
