Setting the fourth via gmaptool breaks the routing for routable maps even though it should be there for setting maps tranparent/opaque is some obscure way different from the general transparent/opaque flag
Could this be the exactly the NOD flag? If modifying this flag breaks routing then this IS a strong hint for influencing routing. Could it be that in this byte one bit is the flag for the presence (or absence) of the NOD table? If this bit is set/cleared then it tells the device that there is no NOD table and therefore no routing is possible.
