Stereo Power on but no audio

ok the first thing i can think of is that when you put the key in and turn it there should be 12 volts going to the system. now seeing that there is no chime and no audio tells me that perhaps your igniton module inside the steering column is defective. your turn signals have a module that is powered on when you turn the key as well. there should always be 12 volts to the ignition module. when you turn the key 12 volts goes to the ignition and all your accessories. like i mentioned before there should be a 10-12 pin wire harness that goes up your steering column. you have to check all the connections under the dash if they are good thios will tell you that the hot feedfrom the ignition is the problem and the module needs replacing... hope this clarifies things for you....pleqase rate thanks
