MM on Road Angel
It's not quite as simple as exporting the map - there's a MM programme that you need to load onto the Road Angel for it to work the maps.
If you have a road angel "adventurer" then the MM is already installed so downloading the map works fine.
The other little wrinkle is that the MM PC software doesn't see the road angel as a GPS - it's a "Device" so you have to find it on different menu option.
