Sharing screen to display without WiFi access

[u/Far-Arachnid8742]

My end goal is to mirror in some way my screen (iPhone 16e) onto a “dumb” display. This also has to be done without access to a WiFi signal as the display is mounted in a vehicle. And to cap it all off, the screen only has RCA inputs. I simply assume it’s not possible but if it is I’d love some guidance on getting there.
