GPS android

[TopEngine]

OsmAnd - only GPS connection is required.
after you download the offline maps, ready to use sya even
without internet connection.
it can even track your speed.

very accurate - used it during our Ilocos trip last May.

I'll be using this android app when I'm going to La Union this August. Which route did you pass from NLEX to MacArthur-Hi-way?
