I'm trying to figure out how to enter waypoints onto an SD card and download them into my HDS-7. Short of manually entering each one, I have no clue how this is done. I tried using the GDM6 program, downladed directly from the Lowrance website, but expierienced and error message when trying to export the files to the SD card. I finally managed to save them to the card, but they were in a "TXT" format and I understand they have to be in a "USR" format. I finally gave up on it and attempted another program. I downloaded EasyGPS and thought with this title, it's the one for me. Wrong again, I couldn't figure out how to change the format of the Lat/Long to degrees/minutes. Sixfin showed me how he used the ozi-explorer program to create a waypoint, store it on a card and then export to the unit. I tried the same procedure with my ozi-program but can only create a waypoint on the maps downloaded from the hydrographix program, which isn't where my waypoints are located. I'm really aggravated at myself that I can't figure this out on my own. I know I'm technologically challanged but am hoping there is an easier way to do this. If not, guess I'll spend some quailty time in the driveway in the new boat downloading the waypoints one by one. Sure hope someone is willing to guide me in the right direction.
