After many requests from users, Google is making mobile Google Maps usable
even when you have no access to Wi-Fi or cellular signal. Just select a
section of a map that you will need offline before you leave home. Then map
then downloads, and when you arrive at the place where you know you’ll be
offline, the Map will work in a very similar way to how it works when
connected.

The map will work with your GPS signal to locate where you are, but you won’t
be able to zoom down to Street View level. This capability will be
available in the next few weeks on Android, but not on iOS.

But Wednesday’s announcements come with some bad news (for Google) from
Apple. The Wall Street Journal is reporting it has confirmed reports that it
will ditch Google Maps for its own mapping app later this year.
