2007 S80 3.2litre AWD 25,000klms (Brisbane, Australia) Gidday! My Volvo radio started sounding soft then loud intermitently on the AM band - FM and CD working normally. Thought it may be something to do with the park assist sensors as the radio volume normally softens when these are activated. Cleaned sensors externally - no difference. Turned park assist sensors off - no difference. Now AM band has died completely - FM band and CD work normally. Any clues as to cause and fix?? Kevin.
