Installed the Lockpick on my 2013 Auto 430N with a generic camera off of ebay. The rear camera video flickers, changes from color to black & white, and the view drops about a 1/2 inch in the screen. I thought it might be a ground so I switched from the black wire on the lockpick to a bolt on the body...same issue. Can anyone help with this? Lockpick, harness, or camera issue?
