Hello, I have now got this box 4F0919142A quite cheap and wanted to have it installed by the friendly one. But as so often the friendly one says “does not work” But as far as I know it goes. Maybe someone has a tip who can install this in the greater Berlin or someone has already installed this thing and can give me a tip. Thanks for the help and always thumbs up for the forum has helped me many times … Greetings Stefan
