CIC -> NBT Retrofit (FSC Code File)

[Emmacorsa17]

Hi everybody.

I've recently retrofit an NBT HU (I think ID4) in my car from CIC (HU_CHAMP2) with Combox.

I've coded my VIN to the NBT,the issue is Navigation greyed out. From research, i've noticed it's due to the NBT FSC file not matching my car VIN. 

Combox removed, Looped the MOST connector.
When i try to extract the FSC file from the NBT HU using ESYS, it fails.
I've seen most people using a Navigator emulator but I want to get and FSC file for my NBT with my vin coded for Australia.

Is that possible?
Thank you all
