Hello- I would like to know if any of you have used some software to bulk enter way points and then transfer to the HDS-5 via sd card.? As you know entering a bunch of waypoints off a chart into these units is a pain. I see that Lowrance has some software called Gdm6, I am assuming that this is for the handheld GPSr units. THe HDS units are not listed in the compatibility list. Thanks
