[FSCmap]

Hey.
Looking for some help, and have got a couple of questions..

I want to retrofit NBT into my F20. It currently has got CIC, with COMBOX with Apps loaded. 
I need to know when i retrofit NBT, can i use the same FSC for Apps in the used NBT unit? I also want to have BMW Live activated at the same time.

Do i need to use emulator, or can i simply just buy a set of FSCs for my VIN from a guy that can do it? 

What about the current combox, what do i do with it when i retrofit the NBT? 

Do i need another controller or can i use my current if i dont care about touch controller? 

Thanks!

You need full fsc set for NBT.
You need to do re-wiring of microphones from combox to HU.
If you have controller on CAN2 it will work. If not - you need to change wiring from CAN1 to CAN2.
Controller can be reflashed.
