Thread: Nuvi Map Theme Files software version 2.70

@Dasilvarsa, you was very insightful. I was hoping someone interested ask how should proceed if wanted to change some characteristic on Garmin Theme, which has not kmtf file available for edition because is embedded in the firwmare, but you went straight to the point ... The hint was to leave a full xml element as example, and not a mere string of the route that would serve only to change a theme ready (France, Nederland..)
Any empty theme as the Polska, Luxembourg, Belgium (or a personal, as yours), uses the same parameters of Garmin theme, unless we add some other, obeying the xml standard as present in the other themes. Now this answered the question of the usefulness of empty Themas present in Garmin gps. They are there exactly for this purpose: easy alteration of one or a few map parameters based on the Garmin theme. Besides providing simple customizations (such as routes), allows for the most curious, identify elements of map and quickly test the layout result in the gps, which helps a lot when you want to make deeper changes, that can be in function of any real need (facilitate traffic visualization, for example) or by mere aesthetic issue.
