I use navigation every day on the iPhone. Google maps is superior in my view (in the USA) over Apple maps because: 1) You can turn off the voice navigation. 2) Google maps show you which lane to be in for an oncoming turn. 3) Google maps have a better "sense" of which lane you are in when you are in an initial turn. Apple maps seem to get lost and start to re-route.
