If you purchase T4A maps as Downloadable links – you will need software to transfer the maps from your PC to your Garmin GPS unit. That is where Garmin BASECAMP comes in.
Garmin BASECAMP is an application which enables you to view Garmin compatible maps on your Windows PC and Macintosh, do route planning and transfer waypoints, tracks and routes between your PC/Mac and your Garmin GPS device. This is a FREE application from Garmin and it will eventually replace MapSource.

Garmin MapSource is a FREE application which enables you to view Garmin compatible maps on your Windows PC, do route planning and transfer maps, waypoints, tracks and routes between your PC and your Garmin GPS device.
MapSource is very similar to BASECAMP, although many people prefer it as it’s easier to use. However, MapSource will eventually be phased out.
NOTE: You must have Garmin BASECAMP / MapInstall, installed on your PC before you can install Garmin MapSource.
