First I exchanged all contourlines to solve autorouting problems that they may cause on other maps. This is due to some changes Garmin will do (or has already done in Mapsource 6.16 and Basecamp >3.0.2) to the autorouting. Installation instructions will be updated in the next few hours too.
Major changes on maps concern naming of ways which are part of routes and/or have highway shields. Also surface values are now better integrated. Also contruction=no is now handled correctly.
Also people all scripts are updated and will now work if date format includes "/" forward slash on Windows.
