a few days ago i left my sunroof open during a big storm there was water everywhere. now my factory radio plays cd's and u can see it light up and change tracks but there is no sound coming from. At first it would sound muffled but now there's no sound. How can find out how much a factory stereo would cost and would it just be the speakers or the radio it self? If i get a after stock radio will i still be able to control the volume and tracks from my steering wheel?
