Rear view camera

Greetings,
I want to have a rear view camera installed on my 2011 model 508.
I wonder:

1. Since software updates will be required, can we have it made by authorized services? Do you know places that do this work in private services, do you know someone? (City: ANKARA)

2. Does anyone know about the price?

Thanks,

teacher first I think if you want to be active on the smeg screen in the vehicle, it is useful to consult the authorized service. As far as I know, I remember that there is no night vision on the original rear view cameras.
