I inherited a Beocenter 7700 from my grandfather and would like to upgrade it to a DAB+/Internet radio using a Digitradio TechniSat 11 IR. However, I couldn't find an AUX input and I'm unsure how to connect the Digitradio (I have already purchased a DIN adapter).
Is there a solution for this? Or is there no way to add an input to the Beocenter 7700?
Thank you very much for your help!
