I put in a XM radio in my 04 X. The first one I bought was the portable kind with the FM modulator that you had to plug into the cigarette lighter. Had nothing but static with it. Took it back and bought the wired modulator type that is permanetly fixed. The tuner box sits behind the dash with the face mounted in the little cubby whole below the stereo and in front of the shifters. Comes with a remote also to tuning is not a problem. Works great and I never use my regular radio anymore.
