[mkgmap-dev] Routing issue to POI

Sat Mar 30 23:38:25 GMT 2013

Thorsten many thanks for your help!!!

My osm generated map is routable and I was wrong in my previous post: I did
some further tests with renaming the base map to  gmapbmap.iii - so the
device can't use the basemap - and I can properly navigate to address/pois,
just in some pretty long routes across countries I'm getting "cannot
calculate the route": so what you stated about the fact the device tries
the next map seems to apply here.

Back to the POI I was experiencing the issue with, if I try to reach it
now, the device does not try even to calculate the route, as if the POI was
really not defined correctly. If I navigate to another POI in front of the
former or to the address where the problematic POI is it works just fine
 so there must be something wrong with it,  maybe that's the issue/bug I
refer to in my first email... it would be nice to prove this (i.e. if the
POI is placed outside the proper polygon).

Thanks again,
Enrico
