Have just purchased a Sony MEX-BT3900U for a 2003 Mini Cooper with Harmon Kardon speakers, together with what appears to be the correct adaptor cable to replace the standard Mini stereo system and have installed it, following instructions on FAQ section of the forum.
Despite power successfully being delivered to the Sony system, there is no sound coming out of the speakers. There don't appear to be any problems with the Sony system (which is brand new) or the adapter cable and the speakers work fine with the existing system. Pictures of the various plus, cables, sockets and the Sony system itself are attached. Any advice on what might be wrong? I've played with all of the settings on the Sony system and tried all the various sources (CD, radio, USB etc.) and can't find similar problems reported elsewhere.
Any help gratefully received!
