Bought a used 2012 volvo s60 t5. Car is loaded wit features, one is the premium sound speaker located on the front dash, most models do not have this speaker..anyway when i play music the center speaker does not seem to be working...only options i have are "sound stage" no controls for this center speaker...is this the subwoofer? How do i get this speaker to work? Is there a update? Updates run $150..
Any help would be usful.
