I need some help! I have a 05 Chevy Tahoe which has 3rd row and has entertainment. I put an aftermarket deck in for a while but my sound would work for my dvd player but the picture would show. I just put my factory radio back in and my sound will not work it had a little bit of static sound. It says rse but wont let sound through. I also tried to plug in headphones in the back and it makes the same sound through the headphones! Can someone please help me?
