Here it is - my first map for Garmin devices specially styled for the average hiker: www.gpxtour.com/all/page/getmap/
The map isn't cut along any frontier - instead it covers the region from Koblenz in the north, Passau in the east, Lausanne in the south and Luxembourg in the west. It style also takes care about the offline usage with a tool like QLandkarte GT, contains separated and switchable contour lines, and is not routable.
From time to time the style will be refined and the map updated. I hope to do that once a month. Have fun :)
