My new Audi built in nav is far worse than Apple Maps. Just an anecdote, but still a data point. Many car navs use aging Tom Tom data.

I recently bought a garmin portable gps for a car without nav and it's really quite good.

Very clear directions when navigating, shows you and tells you which lane to be in, live traffic, touchscreen interface, voice command. Everything is offline so it's more private than apple :)
