Hello municipality, I know the topic has been posted many times but unfortunately I don’t find anything suitable for it. I ordered an adapter cable for the RD4 N1 from Cit and the WS installed today and did not manage to unlock the Aux input. I’m really angry !!! They don’t often get the series to unlock the Aux input, the workshop master said something can only be done with AUX2 because AUX1 is reserved for the phone, but I don’t have a phone. ch do not activate the menuepunkt Autoradio to make possible settings here. Before, however, everyone said there is no problem going on we have already done with Peugeots at Cit but it is not the same. I still have something in my mind as if the PIN-occupation of the plug was wrong, but that can not be so difficult Who has a advice, so that I can show them how to do it as a layman, while I was so happy to hear my MP3 collection in the car this evening. Thanks already m al for your tips. Greetings vanelau
