Having recently aquired a Samsung Galaxy S II smartphone I have been doing a lot of searching around for interesting and useful Android navigation
"GPS Essentials" is a ´Swiss Knife Tool` for the navigator,displaying a wealth of information of great value to safe navigation
. Although,strictly speaking not a navigations program,it can all the same import/export tracks and WPT´s and display your GPS
derived position continuously on a Google
The program is free and under constant development and other great features will be added. It has the most advanced compass
display I have ever seen.
