Google Maps

[t8ntlikly]

I am new to the Google world, and am reading different answers as to using Google Maps offline in the same way as I use HERE Map, or Maps on my Windows 10 Mobile. What I read is that I need to download an area, and only that area will be available off line. Is that correct, or how would I use Google Maps going from say Portland OR to Las Vegas off line?
Thanks

What you have read is kind of true.
Read the following links -

Also, if you want there is a HERE Map app for Android too in the play store.

Also, once you start a trip with data on, you can turn off data and continue to navigate. I'm not sure how many miles or hours you can navigate this way because I don't use Google Maps for long trips.
