anybody know how to fix this problem, or is the radio screwed? I am stuck on 610 WIP - at least its a good philly sports talk show, but every once in a while i like to use the radio when im sick of my CD's. The radio screen can change stations like normal and go from AM to FM, but the signal only comes from 610 AM station. Its all stock equipment. any suggesstions to get this thing going again? I don't like the look of aftermarket stereos, especially considering the extra length on the Delta CC. Thanks guys
(CD changer still works normally)
