I have a 1992 saturn that needed a battery change awhile ago. After the cahange my radio hasen't worked only noise like I have no antenna. The tape player works fine. The digital dial sometimes lights with wrong digits sometimes not at all. I have checked antenna connections and they look ok. Can anyone help with this. I have bought another radio from ebay and installed with the same results. Could the antenna be shot? I didn't think they could be broken. thanks, mike
