Thanks for your reply. Yes, I did check that. On top of that, I tried two different cameras.The four pin connector on the camera can cause problems make sure the pins are straight and make proper connections and that the arrows line up. I am you have checked this but worth a second look.
I'm thinking that my problem has something to do with the RCA wiring harness as I don't get voltage from there. I've checked the connections there as well. No bent pins and securely seated. Either that or something not setup correctly in the software.
