Does GPS iphone 4s use data?

I started using maps app in my iphone 4s while driving. I have limited data package and so concerned about the data being used while gps is enable. I got impression that it only use data when i search the location and then it use the built-in GPS while moving. I doubt it may use data all the time.

I would appreciate if you could recommend the solution.

It definetely uses data the whole time. Depending on your wireless carrier there may be an app available to track your data usage, or just monitor it from your account online

Yes it doe use data but not a whole lot.
