How to save your home and work addresses in Google Maps | Android Central. Google Maps is the best navigation system out there, and it probably does many things that you haven't used yet. One of my favorites is the ability to save home, work and other common addresses, which, when saved, permit me to get the directions by voice. Once you have saved an address, just say "OK Google. Navigate to Home/Office/Courthouse" and the map will pop up. Easy.
