Due to my own carelessness, I killed the battery in my Charger over the weekend by leaving an accessory plugged into the cigarette lighter. After getting the car jump started, my backup camera and video input from the TVandNav2Go mod were inop (get a green screen when you shift into reverse or flip the video switch). After e-mailing Dominic for troubleshooting advice, he told me the black box had locked up and I needed to unplug the power cord to the unit and plug it back in. Problem solved! If you have the TVandNav2Go mod and find yourself in the same predicament, try power cycling the black box. Thanks again Dominic!
