How to Add Maps to MapSource

You add maps to the MapSource software application that synchronizes with various models of Garmin GPS devices by using a stand-alone installation program. Download and install the Moagu "MapSet Toolkit" from The MatSet Toolkit provides an interface for adding maps in the format of Garmin IMG files to the MapSource application. Once you add the map to MapSource, and the Garmin GPS device synchronizes with the MapSource software, the new maps appear on the GPS.
