The OSM-Europ on Your www side is wery good !
BUT PLEAS LOOK
Pleas look at the OSM-Europ-map on a GARMIN OREGON .
It looks in
Germany: very good .
Austria: not usefull , because on the OSM there is an ocean with streets where in reality are mountains .
Korsika : Halfe of the island looks an ocean and
the ocean in the south of the island looks like mountains .
Sardienien : Parts of the island looks an ocean and
the ocean in the south of the island looks like mountai
Kanarisch Islands : has only 1 Street .
I think the conversion of Your map in Garmin-MAP is not ok
With Kindly regards
