Hi Carlos,
Regarding "Region must be defined..." warning, I have added tag is_in:region to some exit nodes and motorways but message remains. How should I set the region to avoid this warning?
It uses the default region name set from the option --region-name. I have since discovered that you can create the highway records without a region and the gps doesn't seem to care. If you don't have a region, gpsmapedit doesn't recognise the existence of the highway but I consider that no big deal. So my current code (patch not yet posted to list) doesn't force you to have a region defined, it just gives a warning. I still haven't found out how to make the gps default to use the exits in the OSM map rather than exits in the basemap. It may turn out that the highway does need a region defined to make this work as we want but it's not yet clear if that's true or not. Cheers, Mark
