I don’t suppose anyone has found a sensible android app that can load a gpx file and give audio navigation directions for a purely offroad route?

I’m off in uncharted lands next week, I have a few routes I’d like to try, and audio guidance via the phone seems like the simplest way to not get too lost…

Quick bump for the morning crowd. Anyone tried OsmAnd? I’m on the road now, can’t download much until I arrive but have a pile of Gpx files ready?
