You have to “compile” a new IMG-File for your garmin with tiles from both sources. In MapSource switch to “OSM cycle map” and mark all tiles you want to have in you new map. Then switch to “the normal map from NL” and also mark all needed tiles. Now check your selection on the Map-Tab and send it to your SD-Card.
There are ways / programs to build a IMG-File without MapSource but I’ve never used it.
