I keep mine in a pocket while cycling, so i'm trying to make an audio navigation help that does not require internet connexion to find route (and that guide you by voice).

It s slow, it eats lots of memory, it does not automatically compute new route if you get far away from the planned one, it tends to give you route information a bit too late, audio is difficult to understand, but it s fun.

Let me know if you would like the data that match Newcastle :-)
