How do I program it to run on the current frequency without paying the dealership to do it? I've been told it can be done but the dealership won't give me the secret handshake to do this on my own. What do I do? The one I got doesn't have the Lincoln emblem etched in it, but it has all the same buttons and the info on the back cover reads identical to the current one I have. It got broke when I took my car in to the stereo shop here to get woofers and box installed. When I got back, the tech was fiddling with it because he dropped it and stepped on it. It never worked afterwards. HELP!!!!
