A new navigation app for Android serves as an alternative to Google Maps with Navigation should travel outside cellular coverage be necessary in MapDroyd by allowing map downloads to microSD storage on the device.
The application uses map data from the OpenStreetMap initiative and the app also uses GPS for position tracking and compass support, but the app does not include other common features such as voice prompts or automatic route correction.
It is available exclusively for Android on the Marketplace and is free.
It doesn’t appear to do navigation. Only an off-line map viewer. Still seems pretty useful.
