I recommend map clippings from bbbike, an OSM map layer made for cyclists.
However, it is very good for hiking.
The difference between other maps and BBBike is the magnification at which you can see the details. Freizeitkarte you have to zoom in more to see the path and it is necessary to move the screen around to see if this path is a good choice.
In fact, there is no tourist layer on Garmin devices, you have to combine with transparent img overlays.
Another place where you can find updated maps for Garmin and BaseCamp is the website opentopomap. You don't have to wait for map updates from Garmin, everything is up to.
