if you have the JBL system without the factory CD contols, there are 2 things you can do.. 1, do what a dealership does and get an FM modulator for the CD controls, or 2, get a ford JBL HU with the CD changer controls, this may be costly, but if the one on ebay is for like $150 or so, I think thats pretty good. although personally, I'd say ditch the entire factory system, but its ok for as long as the subwoofer lasts. mine blew the 1st year I had the truck
