Weird scenario but I’ll try my best to explain where everything came from.

My sister and I both drive vw jettas, same generation (mine is a 13). Her radio broke not long ago, and bought a used oem radio on eBay, but it was a slightly newer version that supports a back up camera. Her screen would show an alert saying “rear view camera not available” something along those lines.

Anyways, I recently got rear ended and paid out my insurance for my car, but the car is drive able and I took it upon myself to fix the damage. I did a rear end swap with a ‘15 Jetta of the same color, which I replaced both the rear bumper cover and trunk. The trunk came with its factory trunk handle back up camera. With this, I swapped radios with my sisters so I can make sure of this back up camera. 

If you take a look at the photos, here is my work. The wire harness I got from eurozone tuning plugs into everything perfectly, the camera, and the back of the radio. I connected the red power wire to the fuse panel up front with an add-a-fuse, and I connected the blue “power antenna” wire to the white reverse light of my AFTERMARKET tail lights (don’t know if it being aftermarket has an effect on the problem). I also grounded the wire to the bolt holding the trunk latch.

Anyways, when I put it into reverse, the camera turns on! I didn’t have a vcds tool to flash it but I still got lucky to get it working, however the picture shown is horrendous. The color is off, and the screen glitches. 

I’m lost at what to do, and I’m tempted just to go to the dealer and see if they can get it working for me, but I hate the idea of having to pay $205 an hour just for them to diagnose it and fix it. Help would be greatly appreciated.

Need help diagnosing backup camera issue.
