Thread: pioneer IP-BUS input questions

I think you might as well just ghet the adapter ( CD-RB20). It's lot of work to do the things you wanna do.

I also got a IP BUS related question. I recently used the IP BUS pinouts and soldered on to the circuit so i can get the AUX IN.
But for some reason I get the music from the mp3 player and also this strange noise. I have the CD-RB20 and as soon as i plug in the IP BUS cable on the back of my HU, the noise stops. Could it be bad soldering? bad grounding? I dont understand what's going on.... please help! If I can get the sound to come out clean I will be selling my CD-RB20.

I soldered ONTO the PCB. my HU has 2 RCA output and one of em i didnt use so i cut the wires out of one of em and soldered onto the IP BUS pins. The wires arent twisted or anythign so maybe I will try that. The tough part was that the pins are so close together i had to be very careful not to solder anything in between them. but since the sound comes out i think its a matter of insulation. I just dont understand why pluggin in the CD RB 20 to it supresses all the noise. If i get this problem fixed I am selling for $65 shipped if you are in US. I just had it for a month or so and paid $70 for it. I also might sell my 12 disc pioneer cd changer i will post it on sale i guess when im ready.

I had this problem when I tried to do exactly what you are doing. The noise is the clock frequency of the display. The reason the adaptor works fine, is because it has isolated inputs... ie the RCA grounds are not ground as they are on the head unit. That's why I abandonded the "all in head unit" mod and kept the adapter.

I hope this helps.
btw I got rid of my pioneer and got a kenwood. the cable is cheaper and smaller for aux inputs
