For those following after me, I found the following from OEMValue.com:
Installing an Aftermarket Camera.
First thing first, make sure you have the reverse sensor wire connected correctly. If your reverse sensor wire is not connected, connect it now before proceeding.
Your aftermarket camera should come with appropriate mounting, one video RCA plug, and two wires for power and ground. Some cameras come with the power wire only and the camera is grounded through the mount.
First, you'll need to purchase a shielded video extension plug that reaches from the navigation system to the reverse camera. 20' is usually long enough, you may want to measure. One end of the video plug will connect to the reveres camera, the other end of the video plug will need to be spliced.
Connecting the Video Wire to the Navigation Unit.
Cut the end of the video plug that is to be connected to the Navigation unit. Once it is cut, note that there is a wire in the middle, this is your positive (+), and a wire on the outside, this is your negative (-). Connect the positive (+) to pin #1 on the reverse camera input and the negative (-) to pin #3 on the reverse camera input. Electrical tape the wires so they do not touch each other.
Connecting Power to the Video Camera.
Tap into the wires from your reverse lights, you may need to use a voltage tester to determine which wire is negative and which is positive. Once you know which is which, splice into the wires and tape the taps. Shift your vehicle into reverse, and enjoy the picture.
Note: If you do not receive a picture, ensure ALL of your taps are correct. Some of our customers report that they needed to reset the memory of the Navigation system through the diagnostics menu in order for the Navigation unit to recognize the camera.
Pin diagram of the 4-pin reverse camera input on the rear of the Navigation unit. Input is located on the right side of the Navigation unit. Should be the only 4-Pin input. Input "G"
Here is my home-made version of the pin-out for Input "G":
