Did all the setup everything but impossible to follow a gpx track with motorcycle offroad, my position is never correct, i have 0 satellites out of 0 ... desinstalled it hope it was a bug but my first ride with it was a nightmare, always changing the next step by itseof by selecting the nearest point insteas of beginning of tracks. Will try once again but definitely not ready to pay for this sorry. I have a samsung S6 in case
