It appeared to be working fine the first day except that I had to make frequent changes to Brightness and Contrast.
Then I discovered that the LEDs don't light up at night.
The next morning the reverse view screen went completely dark (except for the map portion) while driving for about a half hour with only undistinguishable ghosting moving around.
After setting brightness and contrast to max I was able to see a faint black and white picture with occasional bright color flashes.
I assume that this is a camera problem BUT is there any chance that it might be a Z1 problem?
