how do I get my dealer installed backup camera to work, flipped the switch on the master panel, turned on monitor. No picture on the back of any kind.
Camera installed at hitching point is great but back camera will not work at all.
What is missing??
Based on the information you posted about the issue, there's really no telling what it could be other than improper installation by the dealership. Since they didn't tell you how to fix it, means they don't what the problem is. I would insist the dealership fix the problem since you paid them to install the camera. If they want to blame it on Alliance or someone else, then that's a poor dealership.
