2nd gen rearview camera install problems

I know you can disable 1 of the guide lines there in the settings. I would start with that first

 

Hey folks,
Sorry to jump in, I had same issue, NO picture but screen switches to back camera, I am confused with these colors spoken above cuz I have a tundra that am trying to wire, details blw.
My camera has an rca coming out (has 2 leads within it), another power wire (with a pin like you have for flash light charger) with 2 leads. So above threads don't give any ideas at all, I did wire the power cable from camera to Reverse light(both -ve n +ve), the rca plug i took it straight to the rca receiver plug at back of HU.
Wonder what's wrong am doing.?
