CIC business to CIC pro nav coding question

[thedogschuffers]

Hi everyone

I’ve spent a good few hours online and keep finding conflicting answers:

I have an E82 LCI that has S7KA navigation business package from new with a combox

I’ve upgraded to a CIC pro nav and screen from an E81 LCI with 2024/25 map update.

The car has no sound because it’s looking for an amp which I don’t have
The CIC does not communicate with the combox (E81 didn’t have one)
Navigation is blank (needs FSC code)
PDC active but shows E81 graphic not E82

Here’s my questions:

If I buy a lifetime FSC code on a usb will it enable the maps if I plug into the glovebox USB?

Will Bimmer code app allow me to code the combox for Bluetooth music streaming etc or does the vehicle order need to be changed for this to happen using something like NCS expert?

Will bimmer code app allow me to code out the amp to allow sound through the speakers or again does the vehicle order need to be changed for this to happen using something like NCS expert?

I’m not too concerned about the 81 graphic instead of 82 if everything else can be coded with bummer code but I don’t want to go through the expense of buying bummer code and the Bluetooth OBD only to find out I need to get the vehicle order changed.

Any definitive answers would be greatly appreciated.

Thanks
