Back up camera question

[EPierce]

I have a 2007 Suburban LTZ. It has the GPS/video screen on the dash and a video screen between the second row of seats. It does not have the back-up camera. What are the chances that all I will need is the camera and the wiring will already be in place to connect it to the front screen?
