Map Source to Autoroute
There is a way to import waypoints/route from Map Source to Autoroute via Excel, it means a bit of calculating on the way but providing all the waypoints are to the east or west of Greenwich it is automatic otherwise you have to go and check some of the meridian crossing points. If you want the spreadsheet with a bit of an explanation please let me know. When it is imported it matches very well.
