Backing Up Userdata (Waypoints, Routes, and Tracks) From a GPSMAP 7xx Series Device to HomePort
NOTE: HomePort has been discontinued. For additional information regarding the discontinuation, see HomePort Application Discontinued
Before updating device software, it is recommended that you back up user data like waypoints, routes, and tracks. This should be done at regular intervals to provide a good database in case the loss of user data occurs. Backing up the data also provides the ability to edit the information and send it back to the device. HomePort is no longer available for download as service for this program has been discontinued. If the program is already downloaded it will still be available for use.
