I couldn’t get Richard’s cycle map to install in Mapsource, using Mapsettoolkit, but I have found another solution for planning routes to take in the Local/Nation cycle network.
I had to reinstall the free
Mapyx Quo program, as part of a complete software rebuild on my PC, and on opening the program a pop-up offered a free install of OpenCycleMap. I accepted this and now Quo seems to be downloading OpenCycleMap on-the-fly as I move the map around. This slows map panning to an annoyingly slow pace but I can now produce routes (tracks really, can’t find a way to make it routable in Quo) and export the resulting file for use in Mapsource or my GPS.
EDIT: After playing around with Quo the most useful method I have found so far is to produce a series of waypoints for a Local/Nation cycle route in Quo, export that as a Garmin .gdb file, import that file into Mapsource then let Mapsource do the routing on an OSM map.
