Thanks Gerd and Andrzej for your responses. But after doing several tests I still can't get mkgmap:country=NLD working in my lines file. I've attached both my lines file and my address file. I use inc/address is in the finalize section. The boundaries are correct (in fact, these are actually the same as I've been using the past two years), since I can select addresses in my Garmin. Addresses also pop-up when I select a POI.
