Lane assist retrofit in a skoda octavia iii with light assist camera

Hello,

I bought a skoda octavia iii in november 2016.

I included some extras, including light assist. Having this extra means getting the camera (used for traffic signal recognation, lane assist, light assist). I did not include neather lane assist nor traffic signal recognation.

One year and some demostration videos after, I would love to have LANE ASSIST, and I wonder if I need more hardware or software on my car. In the case it is possible, please help me. 

Thank you very much for any help.
