Reverse camera retrofit


Registered User

I'm an owner of a A6 C7 from 2011 (one of the first models in the C7 line)
I have a RMC navigation unit but i will upgrade it later this year to a MMI 3G+ wit Audi Connect.
But now i want to install a reverse camera and i was looking on Ebay to buy the camera and module for it.
I can find those for around 300€ but when i look at the kufatec site, who sells the whole set you need to choose which model year the car is from. Are there any difference between those modules or something?
