I never could get Google Nav to work. It always lost the signal and then had to reconnect with WIFi to start over.
Splurge and get CoPilot. It's a true fully-functional offline Nav app. It lets you select which areas to download, and works offline. It also has nice features like selecting two different parameters to display (Speed, heading, altitude, eta, etc), switching to night mode automatically based on position, and taking user corrections if you find a mistake. Worth the price, especially considering the cost of a Garmin with a much smaller screen.
If you need to check live traffic or gas prices, either use your phone as a hotspot, or pull into McDonalds or somewhere else with free wifi and check it, then continue on. I never really need to, and have successfully navigated with CoPilot all over three states.
Yes. I agree with imkyle Copilot is what you need. Works really well.
According to Google's "Access maps offline" page found at:
"The amount of map that you can make available offline will depend on the amount of storage on your device. If you have limited storage, making a new area available offline may replace your previously offlined maps. If you are offline for a long period, typically more than 14 days, or clear application data for Google Maps for mobile, your offlined maps will also be deleted."
So if you want to use it offline, be sure you have enough storage space available and save the maps less than 14 days before your journey !!
Download Copilot the free version in the Google Play store. It is a Full GPS with turn by turn navigation. The best free gps app. Google maps is good, but if you do not have a constant data connection, than you cannot use it. Make sure you download the maps via wifi connection on copilot before you use it.
First you have to have a wifi connection and you load in Google maps the map sections of the areas that you are going to want to see in gps. Now in Google maps there is a feature that you can save that map to read in off line mode. So you would save all those map areas you want to use in GPS. Then when you are traveling and have no wifi access, you should be able to see where you are with your GPS using your downloaded maps.
Yes you can in the Play Store but I will more than likely cost money.
