Sorry; can't help with herewego.
FWIW I've started testing Magic, Organic, Osmand, and Waze - and thus far find great utility in a new-to-me app called GMaps: https://f-droid.org/packages/us.spotco.maps/.
It is a very quick frontend to online googlemaps which keeps me from having to install the app. It won't provide verbal guidance, but it'll find locations the other apps can't find (street address, campgrounds, local roads, etc.), show traffic, and then obligingly opens one of the other apps providing the address (lat/long) you found.
