The app migrates the maps from your PC to the right place on the memory card of your device and unlocks their codes so that they could be accessed by Garmin MapInstall and Training Center. It automatically sends all current map products to newer devices if possible.
Garmin MapManager is included as part of the Garmin MapInstall download.
Garmin MapManager copies maps and unlock codes into the right place to be accessible by MapInstall and Training Center. To migrate the maps from your computer, download MapConverter onto your computer and follow the instructions.
