Not sure if this applies to the X, but from what I remember with my 325 wagon, any car that was pre 2002 had a different stereo that did not have the AUX port.

If I remember right, the switch to (or from? cannot remember now) Alpine head-units was when they started offering the aux solution, so you may need to buy a newer head unit before you can get aux in your X.

Anyone else? I could be wrong about the X, but this was definitely the case for my 325.

Good luck.
