Mentioned problems with Sony FM/Dab radio, will go off and display will show PHONE- CALLIN PROGRESS. Well have been scratching head for a few weeks, but now I think I may now have an idea what is causing this.Sony radio switched on FM or DAB and it will just go off and display above message intermittently whilst on the move however today was pulling into a carpark front sensors were switched on (default)and radio instantly turned off switched sensors off and radio came back on again? went through this procedure many times sensors off radio came back on. I suspect that the sensors may well be picking something up whilst on move and interferring with radio. Question:Can sensors ultrasonics interfere with a radio signal? Bob.
