[OSM-newbies] GPS rendering of unpaved vs paved ways

[Alexandros Papadopoulos]

Hello

It is useful to know whether a road is paved (sealed) or not when
looking at the GPS. Currently it appears that even tertiary roads that
are unpaved (e.g. http://www.openstreetmap.org/browse/way/25733870)
are rendered in the same way as roads of the same category that are
paved.

I use the maps from http://garmin.openstreetmap.nl

Is this a tagging issue, a rendering issue, or something else? The
desirable outcome would be to be able to take a look at the map on the
GPS and know which roads are paved and which are not.

Thanks

Alex
