I just purchased a 999CIHDSI to replace my aging 788CI.
I exported the waypoints from my 788CI onto an SD card.
If I mark new waypoints on my 999, and then later import the waypoints from the SD card, what will happen?
Will the waypoints from the SD card "overwrite" the new waypoints so that I lose the new ones?
Or, will the waypoints from the SD card merely be added to the new waypoints so that I can see them all?
Thanks,
Ron
