hi, at first the camera didn't work properly. The whole package also requires a Rectifier, ^^12V DC Power Relay Capacitor Filter Connector for Backup Auto Car Camera Filter.^^ <—you can find this on aliexpress. Once the filter arrived, it worked. Car:Mercedes Benz e350, 2010, w212
Just received it, I must install it and I'll give a review update. apparently everything seems ok.
