I have a 2006 silverado, w/my z1 working great.. I hooked my back up camera "video out" to the brown rca jack "rear view camera in" from the z1.. then ground to ground, and red wire to "accesory power". checked all the settings on the z1, and, after 2 hrs. still no picture. I even took the camera back thinking it was bad. when I put it into rev. the z1 goes into a Black screen, w/a warning about images being closer...Thats all I can get..the camera is one of those Ir. cameras , the leds light up on the camera but thats about it. any help would be Great. Thanks guys

Well, you could try hooking it to your TV or even the AUX in of your Z1 to see if anything is coming out of your camera. It's either the camera or the Z1 (or a connection between the 2). I would strt taking things out of the equation. Like take the camera and hook it to a TV, or take the camera and hook it to a different input (aux in) on the Z1. If it doesn't work on any of those, it's most likely the camera.

also, keep in mind the z1 can not display a pal camera, though your tv probably can (newer tv's)

Good point, who makes your backup camera? Is it the pioneer one or some cheapie off ebay?
