I've been using
OsmAnd on Android for precisely this reason. Seems to work reasonably well for ad hoc routing requirements.

I
think OsmAnd can load and follow gpx files but, although I planned to experiment, haven't because I'd rather use an atlas most of the time. Have just checked the website and this is a section
describing this.
On a recent weekend away, I was using OsmAnd for navigating while Hanna was driving. We then decided to visit a National Tyres outlet I'd found using Google Maps so, thinking I'd closed OsmAnd, I started the new route. We came to a roundabout outside Brecon and I was confused because the voice prompts said to take the second exit (which would have been to follow the previous route), while Google Maps showed that we should take the first exit into Brecon. I closed Google Maps when we arrived at the tyre place, and restarted OsmAnd only, it turned out, it'd been running all the while, and been trying to get us to our previous destination!
The reason was that, while routing, closing the application just moves it into the background. To really close it, I should have stopped the routing first.
