I got the USA Spec iPod adaptor for x-mas from crutchfield for the aux input for xm radio (i don't own an ipod) and the install went well. No motor noise and everthing works as expected except for the forward and rewind and change tracks buttons on the stereo while listining to a cd. The buttons sometimes work and other times they take 3 - 4 pushes to get them to work. An example is when I push the fast forward on the 3 - 4 try it will fast forward and when I release the button it will continue to fast forward for a couple of seconds. <p>Has any one else had this problem??
