f you are experiencing a "green screen" like filter that resembles trying to look through a bottle of Mountain Dew when trying to activate the back up camera, you more than likely have a JL vehicle (Jeep Wrangler) with a radio that is not suited for the vehicle and was more than likely mount swapped.
Because the Jeep Wrangler (JL) vehicles use digital back-up camera, and the other Jeep vehicles utilize analog backup camera, that is what gives the green screen/Mountain Dew like visual you see above and will need to be exchanged for a true JL radio.
