As part of some of the smaller new features they kind of rushed over today, Google Maps will add offline features in the very near future. It will join YouTube who also has offline abilities by downloading content to be viewed within 48 hours. Maps offline will offer both offline turn-by-turn navigation as well as offline search. It will still retain everything you would view when connected to a data connection. So don’t look for a watered-down version o f the app. You will still be able to view business locations, auto completion for addresses and such.
We have no word on when it will be exactly making its way to the Google Play Store as an update but we’ll keep you posted when it does.
