I've discovered that the regional government for both Asturias and Navarra have detailed mapfiles of their caminos available for download. The latter covers both the route from Roncesvalles and the Somport route from the Aragon border. The former covers what they call the Camino Costero (both the main route via Gijon and the variant to Oviedo), and the Camino Interior, i.e. the route north from Leon to Oviedo and then the Camino Primitivo to the regional border. I've split all these into the different routes and set them up with Google Maps at http://petersmaps.googlepages.com/google_caminos.html
Note that these are large detailed files and may take a while to load.
The file for Asturias is a Google Earth file (kml), so you can download it yourself if you want to view it in Google Earth. That for Navarra is an ESRI shapefile which I've converted to kml.
