I can highly recommend OsmAnd+ for navigation, it's fully customizable to whatever you want it to do (I was rather suprised it had relevant hiking routes available on my last vacation). You can tell it to use the direction it gets from the compass to calculate your oriantation or, much more sensible for navigation by car, just figure that out from the recent gps fixes.
