I once asked what it would cost to update my Prius' built-in navigator maps: cirka 200 €. And after few years it would be again out of date. I'm not sure whether to blame the car manufacturer or navigator software supplier for the situation, but at least this is very short-sighted thinking from Toyota.
By the way, I still prefer the built-in unit because it has better integration with audio system and windscreen HUD. The usability is actually pretty good despite its age.
Similar issue: the built-in navigator can show realtime location-aware traffic warnings from TMC broadcast, but only if they are non-encrypted. In my country they switched to commercial / encrypted TMC broadcasts few years ago, rendering the feature unusable for my car, and Toyota won't update the navigator unit to support encrypted TMC.
