Hello, on a Mac System, BaseCamp dont´t show a mapname. In the List is an emty Line. I build the tdb after building the map. This are the options: family-id=2020 product-id=1 region-name=SpeicheCanaren description=SpeicheCanaren series-name=SpeicheCanaren family-name=SpeicheCanaren area-name=SpeicheCanaren overview-mapname=SpeicheCanaren show-profiles=1 tdbfile When i build the tdb with gmaptool, the name is OK. What ist missing? I have taken both tdb at this email. SpeicheCanaren.tdb is the one buid with mkgmap mapset.tdb is build with gmaptool Thank you for help. (gmap build with Garmin MapConverter, both, tdb with mkgmap and tdb with gmaptool) Best regaards Arndt
