Your Lowrance HDS-12 Gen3 has limited storage space for waypoints, routes, and tracks. Once you reach that limit, your GPS can't hold any more data. Smart ExpertGPS users have figured out how to eke out every last bit of memory space on their Lowrance GPS receivers. Before each outdoor adventure or visit to a project site, they use ExpertGPS to back up the contents of their GPS, and then clear the GPS data memory. They can then download as much data as possible onto their GPS (leaving some room for GPS data collection out in the field). When they get back, they use ExpertGPS to upload all of their Lowrance waypoints, routes, and tracks onto their computer and save it. Once they've backed up the new data from their GPS, they can clear the memory again, keeping their GPS ready for their next trip.
Backup your HDS-12 Gen3 waypoints, routes, and tracks by using ExpertGPS to transfer them to your laptop or desktop computer. Now you've got a safe back-up of all of the important data on your HDS-12 Gen3, and use ExpertGPS to find and create new waypoints, routes, and tracks to download to your Lowrance GPS. Before you update your Lowrance HDS-12 Gen3 firmware or install a custom basemap, Lowrance recommends that you backup all of your GPS data. ExpertGPS gives you the peace-of-mind that your Lowrance HDS-12 Gen3 data is always safe.
