Hopefully somebody can help me out but I installed the camera yesterday. Everything went well. Back up camera works and I was actually able to put it the angle I wanted but then I noticed when I was trying to use my radio. It wasn't working. There is completely no sound coming out of it. NONE. Not even the beeps when you select something. Can someone chime in if they know what I did wrong. Everything seemed like it was connected fine. I don't want this to be case where I can only have one thing working and not the other.
