The LineMergeFilter does not care about routing nodes. That should be 
the reason why routing fails when using it at res 24.
Anyhow I did not yet fully understand about the relation of the routing 
network (NOD) to the map data at resolution 24. Are there any ids that 
are shared? When selecting a street how does the Garmin find the correct 
entry into the routing network?

Unless there is a concrete example or a concrete explanation why it 
shouldn't be allowed I would allow it.
