Moin together, in my Knaus Ducato a Pioneer Evo is installed in the camping version. I am satisfied with the device except that it goes out at irregular intervals during the ride and then goes up again. Who knows this phenomenon, please also write something. But the biggest problem is the radio reception. Catatrophic! Fiery noise always and everywhere. I have no idea of the technology….can you just unscrew the roof antenna and exchange it? Or do you have to forcibly run away G renew all cables? Thank you for your help.
