A screen for the backup camera doesn't necessarily mean everything has to be through the screen at all.
Most Toyotas I've seen have a screen for the backup camera and the carplay/music/gps console, but everything else is still knobs and buttons.
This is true on both my 2013 and 2026 Toyotas.
I last had that on a (rented) Fiat 500: the "standard" controls (including the monochrome LCD in the instrument panel) looked really clunky and old-fashioned, and all the advanced features (audio, navigation, mobile phone connectivity, not sure if it had a backup camera) were via the (third party, Pioneer) entertainment system which was state-of-the-art with a nice high-res touchscreen. That's probably because this was the more expensive version of the car, I guess the "basic" version only has a radio - no navigation, no backup camera, no nothing. Not sure if it's the same principle at work at Toyota, I haven't driven one in a while?
Also true on my 2020 RAV4 and 2025 Tacoma.
I tried a 2025 Ford Maverick for a year before I traded it for the Tacoma. All the AC/Heat/Etc controls were on the screen. Couldn't stand it. Put me off of ever considering a new Ford again.
