hi sages- need to remove for repair my oe volvo radio in the late model 92 240. radio is above center air vents, not below it as in the older models. haynes description of removal does not seem correct. says to pull off knobs and slip a hook inside the opening to pull a clamp spring . no knobs on thisradio that pull off to access it like that. this is a basic am fm radio with a cassette player. dont want to break any hard to replace plastic panels. bet some of you have done this on a 92 240 and know a quick trick. thanks tons oldduke
