I have a '94 LS400 with the regular radio. When I have the CD player on, there is nothing wrong, but when I switch over to FM, no matter what channel I am on, the radio seems to cut in and out. I have perfect reception, no fuzz, but it almost seems that the radio is blanking out short pauses in the song, and it is at least once a second. When I first heard it, I thought the radio station was playing a song with a corrupted file. Any help is appreciated.
