MapSource™ is compatible with all GARMIN GPS systems except the GPS 100 family of products (GPS 100AVD, GPS 100MRN, GPS 100MIL, SRVY II) and panel mount aviation units. Trip and waypoint planning is possible for all other units; however, the map transfer feature is only compatible with the following GARMIN GPS units: GPS III+, 12MAP, NavTalk, GPSMAP 162, GPSMAP 168 Sounder, StreetPilot, StreetPilot ColorMap, StreetPilot III, GPS V, GPSMAP 295, eMap, eTrex Vista, and eTrex Legend, GPSMAP 76, GPSMAP 176, GPSMAP 176C, GPSMAP 182, GPSMAP 188 Sounder, GPSMAP 232, GPSMAP 238 Sounder, GPSMAP 2006, and GPSMAP 2010. When using a locked MapSource product, the real-time track plotting function will work only with a valid unlock code for the GPS unit being used.

MapSource software allows you to view color maps on a personal computer, with zoom and pan functions for easy map browsing. Use the trip and waypoint manager functions to create waypoints, routes, and tracks, and transfer them between your PC and nearly all GARMIN GPS units. This is excellent for planning your next outdoor adventure, business trip, vacation, or recreational outing without ever leaving your house. For those units that accept the map transfer feature, users can also select individual maps in areas of interest and download the selected maps to a compatible GARMIN GPS (see product list above). Simply connect your GARMIN GPS to your PC using a PC interface cable. Select the map areas on screen, and with the click of the mouse, the information downloads to your GPS. Some units require a GARMIN data card to download.

MapSource Unlock — Applicable only to City Navigator, Fishing Hot Spots®, City Select, BlueChart™.
