When I want to listen to DAB+ radio stations all I hear is hiss but no sound. What is wrong?

AW: The Z-E3756 features an integrated DAB+ twin-tuner. For the reception of digital radio stations, an antenna supporting the DAB standard must be present in the vehicle and connected to the device.
If your motor caravan does not offer a suitable DAB antenna ex works, it needs to be equipped with an aftermarket DAB antenna or DAB splitter, to enable reception of digital radio programs.
