Well I can't see what it does with gmaptool. Maps are still 1 3 17 12  
according to gmaptool and setting 1 3 17 13 breaks autorouting.

I am pretty sure that if the requisites don't break autorouting when 1 3 
17 13 is set, that then the 3 tile problem would be solved too. For 
Garmin maps, setting 1 3 17 12 like mkgmap does changes nothing, routing 
still works as expected. So if on Garmin maps one can change it to any 
value, it should not break when doing the same thing on mkgmap created maps.
