Mike, thank you for posting about the camera. When we bought our PC a couple of years ago, the immediate and about only disappointment was the camera. In a word, it is sorry. I could use more sophisticated language to describe it, but "sorry" says what I really think.
For our previous rig, I had purchased a "Special Purchase" at Sams Club of a seven inch wireless rear view camera. I installed it so that it was always on and found that it worked perfectly for my application. The monitor was as clear as could be and the color resolution was excellent. I wish I had removed it when I sold the rig because I would now install it in the PC. Maybe my experience is unique, because some say they get lots of interference and inferior signal with wireless, but it mine worked great and was fully visible in any light regardless of the sun position. Not so my current camera. I can barely see it and the screen is smaller.
Before spring, I am going to start research on Amazon for a replacement. They have a lot of wired and wireless options on the site. Please keep us posted how you rework your camera. By the way, the wireless one I bought at Sams: $79. Seventy-nine bucks!!
