The native BB10 Maps app still works for me, with voice turn-by-turn navigation.

In my experience, 'search' seems better on the Maps app than NavFree, which I also have. The NavFree maps display on the Q10 screen is really small because of all the header road info display, and I prefer the larger, less cluttered display of BB10 Maps. Having said that, I have noticed in recent use that Maps has struggled to keep up with map download when on the move, and the background map can disappear. So it may be that BB10 Maps will become increasingly useless :(
Several options remain on BBWorld, and some be worthy of further testing
