RS4 B9 stolen mmi 3G

[T33JYY]

Hi I had my MMI unit stolen when I left the car open.. I brought one off eBay as Audi wanted near 4K with the exact part number but from a A4.. I’ve had it coded by Audi and have no lights on the dash but can’t seem to get the 360 cameras working!! I’ve been told it’s because of the software on the mmi is not suitable for the car as it a4 not rs4!! Surely they could change the software on it?? I understand it won’t be under warranty and thinking there just looking for the 4K parts sale ?? Any help would be grateful
