@W0LFB3AT5: Built in. Open maps, click the 3 bars in the top left, scroll down to "offline maps". Follow the instructions and select the map area you want, zoom as needed. Repeat for all areas. Wait for download to finish. Done.

Obviously use wifi.

@NotMeNotYou: dude! You're a lifesaver. I've been using my phone wrong this whole damn time then! Lol 4 years and still using it for online purposes. Thanks man
