Having created a custom route on BC I've been having problems transferring the data to the Zumo 660. If I use the Device Transfer button I get a message saying the route has been created on a different map (!) and asking if I should recalculate. If I select "no" and carry out the export and then fire up the unit to view the route then the route is recalculated in any event and does not follow the route created on the map - it seems to have been recalculated to a 'shorter' distance but deviating to my custom waypoints. The same happens if I select "yes" before the export.
By trial and error I have found that if I drag and drop the route etc to the "card" icon below the device name in BC then the route on the device is the same as on BC.
Comments please!
