Using iPad air as GPS

If I buy an iPad Air with wi-fi and Sprint, but do not get a service plan, how can I use it as a GPS in the car?
Do  I have to download a map app and what would be the best way to achieve ths?
Thanks, all you smart, helpful people!

Answer 1

Michael is, of course, correct.  Here is more detail.
GPS signals are separate from and completely unrelated to both the Internet and the cellular telephone network.  GPS signals come directly from the GPS satellites.  They provide signals that allow GPS receivers to calculate latitude and longitude information.  Map software then takes that latitude/longitude info and converts it to land mass, roads, bridges, highways, buildings, etc.  Navigation software is "map software on steroids."  It goes one step further in that it provides real-time directions to enable you to reach a desired destination.
Most navigation software stores the maps right in the iPad/iPod/iPhone but a disadvantage is that the maps must be periodically updated (perhaps once/year).  The Internet is not required to use the system but it is required to update the maps.
Some navigation software gets the maps from the Internet and requires an Internet connection to function but an advantage is that the maps are always up-to-date.
The WiFi+3G/4G iPad and the iPhone both have a GPS receiver.  The WiFi-only iPad and the iPod do not and these devices require an accessory.
