I just bought a 2005 Cobalt and everything on the car is great except for the volume on the stereo. The radio works fine but whenever I try to turn up the volume, the radio either turns off or on. The volume doesn't decrease or increase. Any ideas as to why this is? Thanks so much. Oh, and I also read in the manual that the car has an auto volume where it'll change the volume automatically to compensate for the wind and speed of the car or something. I don't know if this has anything to do with it. Thanks.
