The first new feature is the ability to switch to using only Wi-Fi connectivity for location navigation. This comes handy in situations where you come across a free Wi-Fi network while navigating with Google Maps, and you want to save your mobile data.
To use this feature, simply grab the latest update on the Google Play Store using the button at the end of this post, slide to your Settings Menu and check the place where you would normally find Offline Areas; it has been replaced by a Wi-Fi Only option, which you can enable to stop using your cellular data and load your navigation data through Wi-Fi. This feature may excite those who have the capacity to purchase Wi-Fi data bundles.
Product Manager for Google Maps, Amanda Bishop describes a scenario in which this feature is useful in a blog post:
The second new feature in Google Maps for Android allows you to download location and navigation data for offline areas to your SD card instead of the internal storage. This is particularly useful for those using low-end and mid-range smartphones that possess meager amounts of internal storage.
With this feature, you can now kill two birds with a stone; save for the rainy day when you have abundant megabytes for browsing by downloading map data for your frequent locations to your phone for offline use, and salvage the internal storage on your phone if you have an external SD card. Users of high-end smartphones with ROM capacities of 64GB and upwards won't be too concerned with this.
Amanda Bishop also described a scenario in which this is useful:
Entry-level smartphones come with internal storage capacities as low as 4GB, while higher-end models range between 8GB and 32GB. For many of us, that’s not enough for all the videos, music, apps, and photos we cram onto our beloved smartphones. To ensure that Google Maps users with any storage capacity can download and use offline areas when they need them most, we’ve added the ability to download your offline areas to an external SD card (if your device supports them) on Google Maps for Android. Now you’ll never have to choose between snapping more food photos or the ability to navigate offline.
To enjoy these two new features, you have to update your Google Maps to the latest version. Grab it in the Play Store using the button below.
