I bought the HK3 Hardwire kit and had them both professionally installed yesterday but so far I have zero parking files. I have it set to 3fps. I just noticed that the camera goes totally black every time I turn the car off, I can't get it to turn on at all unless the car has power. That... doesn't seem right? I know absolutely nothing about this stuff and want to confirm that this is an installation issue before I go back and ask them to fix it. What do you guys think?
