So I just picked up a 17 Aventador S. The car has the sensonum stereo. The radio plays very loud, however when I make a phone call I can barely hear the person talking no matter how loud I turn the volume up. The volume on my phone is turned all the way up as well. Yet unless im am sitting still and not driving the car I can hardly hear the other person talking. So radio goes plenty loud, but phone I cant get any volume out of it at all. My Huracan was the same but that had an aftermarket exhaust so I thought it was that. However the A has stock exhaust and the volume level is just as low.
