Hey Mark,<br>
<br>
yes, downloading only the graph changes is possible at the low level -<br>
there is currently no OSM changeset reader or similar.<br>
<br>
But you already indicated that a fresh import is already better and so<br>
... if you want to integrate your changes while import have a look into<br>
the OSMReader where an edge is created via "graph.edge" and you can<br>
manipulate the access flags too.<br>

</div>Exactly.<br>

<br>
</div>Sure, you can do this too. But having the entire up-to-date graph (be it<br>
with or without shortcuts due to CH) on the device probably makes more<br>
sense in your case.<br>
<br>

Peter.<br>
