Apple launched its own service in early September and dropped Google Maps when it launched the iPhone 5 and rolled out iOS 6 an upgrade to its mobile software platform.
Users complained that Apple's new map service based on Dutch navigation equipment and digital map maker TomTom's data contained errors and lacked features that made Google Maps popular.
In October Scott Forstall a long-time lieutenant of late Apple co-founder Steve Jobs was asked to leave the company partly because of his refusal to take responsibility for the mishandling of the mapping software.
While Apple Maps offered soaring flyover views of major cities it had no public transit directions limited traffic information and obvious mistakes such as putting one city in the middle of the ocean.
This led to Cook apologising to customers frustrated with the service and in an unusual move for the US consumer group directed them to rival services such as Google's Maps instead.
