    you see, both c2 and c3 have the cd changer connection

    which one is it really? or both have to be connected?

    or c2 for certain cd changer model and c3 for another cd changer model?

    What are you trying to accomplish? There are plenty of premade aux adapter cords and Bluetooth systems available that plug right into the back of these radios. Looking online may help you figure out what you need to do, based on the photos they show

    i want to accomplish 2 things

    1. to add a line in, as you said, bluetooth. That is the easy part.

    2. I am trying to understand why does the cd changer need both c2 and c3? isn't one enough? Why need so many pins? (5+3= 8 pins needed)

    Not sure of all the details, but part of it lies in the Bluetooth for phone use. I bought a iPhone/Ipod lightning cord adapter that plugged into the C3 aux input on the back. Purchased back in 2015. Later, around late 2017, the Bluetooth phone quit working after a software update in IOS, I could hear, but the microphone no longer worked. I contacted the company in 2018 that sold me the cord, and I had to send it back and they modified it for a small fee, and now it uses both C2 and C3 to work correctly and I have Bluetooth functioning again. (at least I believe it now uses both C2 and C3...I would need to look and see to be certain, but that is what I recall)

    ok, all done. BUT
    i found that if I don't connect c2, there will be no sound. Both c2 and the c3 have to be connected. Basically the becker thinks that I am playing a CD changer instead of the actual bluetooth receiver at work.

    problem.

    1. In order for the head unit to recognize there's a "CD changer", my CD changer magazine has to be in. and while I am playing bluetooth music, the cd changer is working! If I remove the magazine, the bluetooth will stop working!

    2. my single cd at the head unit will work , but there's no sound.

    Have you consulted with the seller?

    update: the seller doesn't know anything...LOL

    so, I wrestled with the becker 6112 on the 430. Turned out, if you press "i" button, then select settings, you'll find the "aux". Finally, I can take out the 6 cd magazine and still be able to listen to my bluetooth ( from my android phone in my case) . And the head unit would display "AUX"

    still, if I switch to single cd, it has no sound, although it plays.
