Garmin has a POI loader for downloading POI files into your GPS. These "point of interest" files contain what you can think of as a waypoint however, they can be categorized into meaningful groups.

I recently started using a Garmin Zumo which allows POI files to be downloaded and takes advantage of the category feature of the POI Loader utility. To include categories and subcategories on your Zumo each POI file needs to be placed in a unique category folder on your computer. I start off with a folder called ‘My POI' which I will later point the POI load to. This folder does not become a category but all folders created in it do. The Ducati Dealers POI file has this file structure.

In the Ducati Dealers folder you've got all the POI files in GPX format.

To load these on your GPS unit download and unzip the files below keeping the directory structure. Point the Garmin POI loader at the My POI folder and select the manual method for loading the files.

Once downloaded into the Zumo this is what you get.
