hi my proton saga blm's radio signal seem frequently cut-off, like got sound and then suddenly no sound at all, then 1 second later got sound back... when i just bought it, i already notice this problem but thought that the specific radio channel's signal is weak, so thought its a normal thing. now after using it for quite some time, i notice most channel like that, its quite random but quite frequent. Quite annoying. So i wanted to check with u guys whether is it normal for blm model or shud i sent for repair. Cos i think quite hard to proof cos its random and scared those technician balme the radio channel being weak signal and nothing wrong with the car...kindly advise me. Thanks
