This aftermarket radio was installed before I bought the car and has worked fine for 2 months now.Two nights ago as I was parking the car the sound cut off on the radio. I messed with it for a min with no luck and just got out and brushed it off. It hasn't worked since then. I have checked the fuse in the driver side kick panel (#17) and the engine bay (#38) and found that both were good. The radio powers up and the screen and whatnot works fine. There is just no volume at all from the speakers. Any suggestions?
