I'm actually getting ready to disable the antenna myself. Now it goes up and down whenever the stereo is on (cd player, XM, or radio). I just purchased a small toggle switch from napa for $2 and going to put it right under the radio and wire it into the middle of the power antenna turn on wire. That way if I want the regular radio and not XM (I have no idea why), all I have to do is flip the switch and its up. Also if you leave the switch on, it'll still go down when you shut off the car
