[mkgmap-dev] Stronger Intertile Routing Problems with Basecamp4.2.1?From Felix Hartmann extremecarver at gmail.com on Tue Jul 9 20:42:53 BST 2013
Oh and I forgot to say, I know for certain it's the tile boundaries - because identical map with different split tiles, calculates the route just fine. Too bad we don't have differently split tiles on identical original garmin non NT maps, to see if there are problems too!
