Hey Guys,

I got a 2011 328xi that gets stuck on "Please wait" when trying to select telephone / bluetooth.

Owner was told by dealer that it was a combox issue. He replaced the combox with a used one now gets the SOS failure error, SOS failure error goes away when putting the original combox back.

I can't code the combox, media fails in communication and here is the screen of what the ISTA control tree looks like:

Why is CCC in the control unit tree when this car has a CIC, it displays it as: CCC_0xA0

and for TEL/MULF  it says _0x36, anyone know how to fix this, i can't code the used combox we put in, no communication, and can't code the old one either

if you can communicate with the old Combox and not the new used one, then the new used one is faulty.
if your most bus is down, it is normal to show CCC until ISTA identifies the correct headunit.

the old one is problematic as well, although the SOS error goes away, I am not able to code it, still comes up red
