Driving yesterday I could hear this "click-click-click" as I drove, so I turned off the radio to hear better. Hmmm, sound went away, oh well. I turned the radio back on, and the noise came back! I repeated this a few times before I concluded that my power antenna was not shutting off once it reached the top if it's travel. Yech! Does anyone have any ideas or solutions, besides the $169.50 one? Gus Schlachter Austin, TX 4695
