I have a 2006 CL500. The CD player, CD changer and even Sirius satellite radio work just fine, but the regular radio does not. When I go to the radio mode, I can't get any sound to play. It also does not pick up any channels when I try to scan for channels, which leads me to believe that something is up with the antenna. Does anyone have any suggestions? Any help would be appreciated. Thanks!
