Hello, I am asking for help with connecting the aux cable to the RDC300 radio. My problem is that I bought a cable from the Quadlock connector on the Allegro (visible on the right in the picture) after connecting the radio does not see it. In googles I found the pins of this radio (visible on the left in the picture). After looking at this problem and checking the connections, I checked that according to the purchased connector, the weight of the jack cable is 2 pin, the right signal is 7 pin and the left signal is 1 pin. And from the visible observations you can see that, for example, the right signal falls on the nothing pin. Please help me solve this problem to activate the aux. Thank you for everything in advance.
