Common question, so fret not. First, you must have a 3G capable
iPad to have an internal GPS. That confuses people. It is just how they package the unit, with the two together. You do not need cell coverage, nor do you even need to sign up for the 3G service for the GPS receiver to work. If you do have a cell signal, the ipad will have a general idea where you are on the planet, which makes acquiring the appropriate GPS satellites faster, but once you have them, you're as good as any device.
If you do not have a 3G capable iPad, you can get either a plug-in gps receiver or Bluetooth receiver for it.
