When the name is missing, my Edge 705 usually says "Jälki" (the Finnish
for "Trace" or "Track") for cycleways, footways and highway=service.
I do not know of a way to assign a "null" name in mkgmap, other than
omitting the "name" or "default_name" action.

This is another example of it being impossible to satisfy everyone's
needs with a single map.  As a bicyclist, I very much appreciate having
street names on cycleways that are running next to a highway.  In that way,
the turn directions become more meaningful.

Would it be possible to hide names in a map overlay?  Say, have several
overlays on the base layer:

* contour lines
* highlighting of paths that are not for (motor) vehicle use:
 * hiking
 * mountain biking
 * horse riding
* routes and stops for public transportation
* motor vehicle overlay (hiding some names and the like)

If the Garmin routing subsystem could utilize data from map overlays
(can it?), the motor_vehicle=no stuff could be omitted from the base
layer and the desired overlays enabled by the user on a case-by-case
basis.  For example, mountain bikers and "normal" bicyclists would
prefer different routes and select different map overlays.

Best regards,
