From the developer:
JaVaWa Device Manager helps you to manage the contents of your Garmin device and accompanying (micro) SD cards in an easy way. The program performs an exhaustive check, reports potential conflicts and provides a wealth of information about the maps in your device or on your SD card.
You can secure contents of your device (or SD card) through a backup, and restore it later.
