For navigation we use a 2nd hand OP6, running #LineageOS connected to a #SON28 dynamo via #sinewavecycles usb converter.

The cycle routes in France are very well and we followed them using #osmin in cycling mode. If we plan, we use #brouter which is excellent.

To find toilets, drinking water or shelters we use #OSMData via #organicmaps or #osmin. We also contribute missing data via #Vespucci from #fdroid
We believe in #foss and drinkingwater spots are essential (stop bottled water).
