Garmin RoadTrip

RoadTrip allows you to transfer waypoints, tracks, and routes between your Mac and Garmin device and manage your data using your Garmin maps.

RoadTrip provides the ability to search for points of interest from the convenience of your Mac and then send the locations to your Garmin GPS.
The included utility MapManager copies maps and unlock codes into the right place to be accessible by RoadTrip and MapInstall. To migrate the maps from your Windows PC, download MapConverter onto your PC and follow the instructions.
