Is there any program that you install on the navigators and similar for the droid. It is called GPS tracking. Favorite points are, in my opinion, at all in any navigation program. So it is not connectivity to the Internet must be downloaded to the card, i.e., another plus in the direction of the programs for navigators. Their only drawback — they are paid.
From the examples, I use Shturmann. Also suggest googling what prog used to Garmin which is designed for fishing / hunting / tourism — just what you need.
