Space Star (2016) – Radio installation?

Hello, I will soon take possession of the Space Star in the 2016 variant. Unfortunately, it was only enough for the basic equipment. Since I don’t want to do without music, I would like to upgrade at least one radio. Loudspeakers seem to be already installed according to the description, which makes me rather relieved. However, for the radio there is no simple insert, as I know it from “formerly”. Instead, a large plastic panel is located here, where with larger So, what kind of device can I install here & how is it supposed to work? Are there devices that are designed for this “form factor”? Is there absolutely hundreds of euros? Maybe there are also built-in frames in which you can then put a normal radio again? Questions about questions – does anyone know about this?
