The sendero look around app is out for android, and works really well. For turn 
by turn directions, use google maps, it works well and is free. If you want to 
virtually explore the map, you can use a free app called intersection explorer. 
This may not provide every single feature of sendero GPS, but it comes very 
close, at a much cheaper price.
