If you are a QGIS user, open Plugins > Manage and Install Plugins… and search for GarminCustomMap. You may need to zoom in to have the map appear.

In addition to ArcMap, you should also have access to a text editor such as Notepad, an image editor such as the GIMP or ImageJ, and Google Earth. This video illustrates the export process, plus some quick edits you can make to create a Garmin-compatible KML file that will work on most recent map-enabled Garmin GPS units, such as the Dakota, Oregon, Colorado, Map78, map 62, and the eTrex 20 & 30. The exported KMZ file will open in GoogleEarth or other KML file viewers, but the default image format it creates is not compatible with Garmin GPS units.

ArcGIS includes a Map to KML tool that will create a KML file from an existing map document.
