mangoal Dash Cam Power Adapter for Mazda with 10-Pin sunroof Plug (Model B) – Hidden Cable Kit for GPS Radar Mirror Camera, Plug & Play Fits All Mazda Models with sunroof

If you have a sunroof (I believe all cx50s do) , this should be an option for powering your dash cam. I have the mirror with homelink so I purchased their mirror power option, but this connection to the sunroof actually looks easier to install : https://a.co/d/08Dt23Nf
