I have been without sound in my vehicle for the past 7 months. The radio comes on and the antenna is working fine, but I'm not getting any sound. Can anyone help me solve this problem? Yes, I tried turning it up. Nothing. I'm also getting a whining sound coming from an apparatus packed in foam on the right back end of the trunk. What is that? Does anyone know how to stop it? It only makes the sound about 5-8 times after the vehicle is started up. Well, let me know if anyone has faced these problems before.

Thanks,
