reverse camera

My son has just bought a 2018 Crafter with a traditional radio (see image). I know there are multiple Android Auto, Apple CarPlay conversions available that include the radio / vent surround. I assume when purchased they all come as. “Plug and Play” swapping with the original radio. Please...

I'm wanting to get a reverse camera fitted to my crafter it already has rear parking sensors. Is there any particular I'll need because of having sensors. Anyone got any links to cameras wired to rear view mirror? Any help would be appreciated. Thanks
