This mess up was major. Apple got rid of Google Maps as the iPhone's default navigation and replaced with their own. It was called Apple Maps, despite the fact that it was hardly a map. A Tumblr named The Amazing iOS 6 Maps was dedicated to the pitfalls of the app, which would often lead drivers very, very astray (like, into the middle of the ocean).
The then-newly appointed CEO Tim Cook even issued an unprecedented letter on the matter and offered some much better alternatives. Nice of him.
