Navigon has updated its iOS GPS navigation app with several important updates, including the possibility of downloading U.S. maps state by state.
This can prove quite handy by saving you up to 1.7 GB of storage space, the size of all of Navigon's maps. After you download the app, you can simply select which maps you want to upload to your phone.
The new version also brings a new interface, the possibility of zooming and pinching the map in 3D mode as well as an in-app purchase option for quarterly map updates.
The formerly privately-held German company Navigon was acquired by GPS giant Garmin in June 2011. Financial details of the acquisition were not disclosed.
