I’ve got a cheap Bluetooth kit for Concert 2 single din, which will just allow Bluetooth music playback. (That’s all I want.) It fits into the CD changer part on the rear of the stereo unit. After removing the stereo to plug it in, I have a 20 pin plug which covers the CD changer however it has no pin terminals in as No CD changer is fitted. I’d like to pay someone to reseat the five pin terminals of the Bluetooth plug in to the 20 pin plug/ harness I’f anyone can make this work? I’m based in Leeds. Please look at the photo attached for a better understanding if I’m not making much sense, the two plugs need combining or the 20 pin plug down sizing to a 12 pin plug?
