FFS. Several people have done it themselves and not needed to code anything, but one person tells you different, and you doubt us.
For the sake of unclipping a piece of trim and undoing 4 screws, why don't you just plug the new radio in and see what happens? 5 minutes and you'll know, then you can come back and tell us all what happened.
If you are retro fitting stuff like rear camaras, parking sensors, bluetooth, mdi, etc, they have to be coded to the car, NOT the radio. If those items are already fitted and working in the car, they won't stop working when you change the radio
