I'm attempting to download the waypoints/tracks in a GP30.
Connected to computer with opto4 data cable and USB-serial adaptor
I can see the regularly repeating intervals of NMEA data streaming from the GP30.
When I go to send the data to PC, it stops the repeating NMEA data after "are you sure" on the menu (figure 7-16) and "Hit any key" (figure 7-17). I hit a key, and the NMEA data starts flowing again. Nothing comes across regarding waypoints/tracks.
I have verified there are waypoints in the GP30 to send.
I have turned off DGPS as per page 7-6 note2.
I presume I'd see a stream of sentences containing waypoint data while it sends things?
I also tried the Andren.com Furuno loader and it did not detect the GP30. Data is being viewed in both Putty and Mttty (but not at the same time)
