Contour Enthusiasts Group Archives Forums Modifications Audio cd changer with fm modulator

i'm starting to think it has more to do with the ford cd player than the changer, when i unplug the antenna from the stereo and into the modulator, and the modulator into the cd player i lose sound, the radio tunes to the appropriate station, but I can't hear anything. If I change the preset on the modulator to the other frequency the radio tunes to that station.
