Best GPS app for iphone that uses the least amount of data?

Of course apple maps are built in and google maps
Seems pretty standard. Do you guys know of gps apps that don't burn through data, I'm not sure if these apps already on here do or not.

It depends if you are willing to pay. For example, TomTom makes an iPhone app that has offline maps, and you can probably be assured the maps are pretty accurate. The only free one I've tried and had reasonable success with is NavFree, which uses OpenStreetMaps (where people around the world pitch in to make maps) and the quality of which depends on where you live.

Any map application is going to use lots of data to download map details, unless it includes offline maps, and if you use offline maps, you'll chew through your storage space instead of through your data allocation. Either way, resources are used. Using a map view instead of a satellite view can help a lot, since satellite views require transfer of photos, whereas plain map views can be much more compressed.

I would like to recommend these apps
-Waze
-Google Maps
-Maps on Demand
-Maps on Board
-Navigon (Paid)
-Magellan RoadMate (Paid)
These apps are very useful.
