I use the latest OsmAnd 1.6.5 beta with the newest “germany - niedersachsen” offline maps from 22.01.2014.
But the routing is at some points wrong.
Here a example:
from “cuxhaven, Haydnstraße” to “cuxhaven, Geinrich-Grube-Weg” OsmAnd is not able to see the main road way.
The problem ist the crossroad, OsmAnd is not able to routing the way in the direction from south to north obwohl although this is one of the most important streets in cuxhaven.
I try this routing with differnt smartphones and with older OsmAnd and older offline maps too, but the problem is always the same.
screenshout: OsmAnd shows an obviously wrong way.
screenshout: at this crossroads OsmAnd is not able to routing the way in the direction from south to north
Likely that is because Catharinenstraße has a maxspeed of 10 km/h whereas the parallel Bernhardstraße has no speed limit (just the one which is assumed for residential streets, so likely the assumed average speed is higher).
So, the routing is not wrong (according to the data).
