Anyone have any idea's what I can do? I just installed a Crimestopper SV-5420.IR into my stock nav using navtool. Picture quality during the day is fair. But at night it's horrible. I figured it was to much light from the license plate lights so i taped them off to see if i was right and i was. As soon as I did the picture quality was perfect at night. Any idea's what I can do or maybe a better choice in a back up camera?
