Replacing combox

[1animal1]

Hi, I am needing to replace a Combox with a replacement unit - obviously hoping the software is at the correct level to integrate with my CIC (going to buy same model ref or newer).

Can anyone tell me - when i upload the existing settings to the new combox via NCS, will this transfer the FSC code? Or can I retrieve this from the old box using Tool32?

I have tried retrieving the old combox to no avail. NCS/ISTA/D can't read the code, despite it showing on the INPA VO list as OK.(I have one last Tool32 instruction to follow to see if i can update the vin that isn't showing on the inpa list). NCS errors when i try to access the MEDIA module for read or uploading original settings, ISTA/D shows the media module greyed out, when highlighted it reads as CMEDIAR variant, but group type TEL/MULF - obviously now aware combox is the MULF2, therefore I won't have any further modules that could be at fault

Here is the options list for the vehicle, so assume I have an FSC code built in.

S612 BMW Assist
S615 Expanded BMW Online Information
S616 BMW Online
