Selling the NBT Evo HU from my 2013 550i. I upgraded to the NBT EVO earlier this year.
What you see in the pictures is what you get - nothing else. I am not sure what is needed to upgrade from CIC to this, I assume just re-wiring.
This is really priced for the HU itself and I'm throwing in the screen as a bonus. Not sure if your original screen can be re-used, which would make it easier.
There are some marks on it, but they are barely visible when the screen is on. Based on what I see, this is pretty common on these screens.
Price doe not include shipping.
