Rear View cameras

[cyclingspongecake]

I would like to fit a rear view camera to my 2017 custom. I've had rear windows fitted so would be nice if I could get one which has the screen built into a rear view mirror - I believe the mount for a mirror is behind the trim on the windscreen. Can anyone recommend a kit for this, pref not too expensive ? I'm not bothered about it being integrated into everything else!

thanks
