There are differences of opinion as to need for a cellular data plan for an iPad to use GPS features. That is the problem. All opinion and no knowledge.
What features, if any, of gps and location services is available on an IPad (with 3g or 4g chips) when one does not have an active data plan.
iPad 2, iOS 5.1
A data plan is not necessary to use GPS on iPad, BUT, the cellular version is required because a Wifi only iPad does not have a GPS chip.
There might be differences of opinion but there is only one fact. A data plan is not needed. Period.
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 latitude and longitude information to GPS receivers. Navigation software then takes that latitude/longitude info and converts it to land mass, roads, bridges, highways, buildings, etc.
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 every two years). 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.
Is data plan needed for gps on iPad
