Hi CT members,

I hope you can help me out.

I have a E60 from 2009. Originally i have CIC in the car with TCU 1.5 and mulf2 high. In my armrest i have USB and AUX (6FL) factory fitted.

I did a retrofit to combox. All the wires are moved and plugged in the right order to the combox pin housing socket. EVerything works fine including USB under armrest. This is connected on black port on combox.

But my AUX is not working. I checked the plug from the aux connector under my armrest and 3 wires goes to the back of the cic in pin 2,7 and 8. In idrive i see AUX and can also select it but there is no sound.

I checked coding and everything seems to be okay. Before the retrofit it was working fine with TCU and mulf2 together with USB hub. USB hub is coded on nicht_active in the combox .trc file.
