Nah, it was relatively common on base models that did not have a head unit with a screen, and that definitely includes Hondas and Toyotas, for example. The most common type of vehicle to use such a setup were pickups. For Toyota, the Taco and Tundra are the only vehicles I can think of which used an in-mirror screen. Honda did it in the base model CR-Z. Ford, Chevy, and RAM did it on their trucks.
