My SLC bought used this year has the command with DAB tuner + Harman Kardon sound system. It is built in 2018. The reception of DAB stations here in Stuttgart is very good, but unfortunately not all. Many stations are missing mainly those of the antenna DE like Beats, 80s80s,90s90s etc, i.e. those of the second federal mux. Have had the car with Mercedes, they found nothing, cause would be: my command would have only DAB and no DAB+. I can’t believe that. In the price list 2018 from Mercedes the Comand was offered with DAB+. Who has an original Comand DAB until BJ 2018 and receives all channels? or has the same problem? To find the cause, I need information, someone has a Comand until BJ 2018 and receives all channels, such as Beats, 80s80s,90s90s etc.? Does the Comand with DAB have a separate radio tuner? or is everything installed in the Comand? Could the cause lie in the defect of one of the two antenna amplifiers, which left and right in the A column are installed? or can anyone give me more helpful information? Thank you very much in advance. Greetings Martin
