Hi Andrzej,

what do you mean with "break continuity of roads" ?
My understanding is that such a relation is only used at nodes where mkgmap 
will create a so-called route node.

Hi,

I have tested these example too, BaseCamp gives correct messages. I can
only suggest for mkgmap to break continuity of roads at junction
indicated by "through_route". This could give more warnings from navigation.

I'm not sure how popular "through_route" is. If there are redundant
cases, break could be limited for roads type 0x01-0x03 and when
"through_route" turns with acute angle. Too many breaks would degrade
routing performance.
