You may or may not have noticed but Google Maps’ navigation mode has been using Google’s old voice search functionality all this time. Finally, that’s going to change in the near future. Google announced at Google I/O 2018 that Google Assistant is finally coming to the app. It’ll be rolling out to Android devices this summer and will be coming to the iOS Maps app later in the year. Unlike it’s usual format of having Google Assistant take up most of the screen, on Maps it’ll show up as a small bar at the bottom of the navigation screen.
