Getting Numbers off a Furuno Navnet VX2 in Readable Format
Does anyone know of a way to get the numbers off this machine?
I can download to an SD card but have not found a way to open the files in a usable format so that I can read them.
Furuno has a cable that you can use but it is for download / transferring, again, not readable.
Gonna need to find the old Furuno planner software or another program to convert and mange them as a spreadsheet.
What I intend to do is to take the few manually entered way points presently stored on the machine, and then attempt to do a "Save to Data Card" function coming off the Furuno unit.
Next - remove the card from the unit and open it on my laptop, using Notepad or Wordpad, where I can analyze the heading/footing and data sequence of the output data. There has been some confusion over the file name, file extension, and Card formatting. Getting an output file of valid data should allow me to do some forensic investigative work, so that I stand a chance of matching what is required to upload.
Step three - use that heading/footing data string and file name extension to match what I have already done in MS Excel... (saved the data string for each point as an MS DOS CSV [comma separated value] file).
Step four would be to see if the changes I make to the computer data file are importable back into the NavNet 2 display and get reasonable data. Again - its hundreds of way points, which would take me about two minutes each to input using the suspect trackball and flaky 10-key unit interface.
What the fine Furuno manual reveals is that the data sequence is quite different than what is output from Google Earth, Garmin, Lowrance or any other geo-point service. Manual page 6-5 of my fine NavNet2 manual describes the Waypoint Data Format, and sections 6-1 through 6-3 describe all of the other theoretically possible functions dealing with data storage. What is unknown for me - is what is not operational at this time in the unit, what should be possible with the correct formatting, and what is not possible due to unspecified or undisclosed errors in the unit/operator interface. Needless to say - my unit has bugs and plenty of deficiencies.
And to the OP, Marlin - that cable that you mentioned is available from your Licensed Furuno retail outlet for just $150. That would theoretically connect your unique 7-pin data port on the Furuno unit into a USB interface from your PC, where you should be able to view and manage the information in a program like GPS Utility. The documentation Furuno provides with the unit does not disclose the pin connections to build one of these data cables for yourself, nor where to locate their special 7-pin connection, but someone that follows THT probably has insight on how to get 'er done. I would be VERY interested in receiving that information.
Marlin - Please keep me abreast of your progress, and watch for my reports on any success in using this unit/system. (1834C dome / GD-1920C display / GP-320B GPS Receiver / ETR-30N Fish Finder / plus Heading Sensor)
Maybe by the end of the season, we'll both have units that do what we want. :thumbsup:
As noted above, the GPS Utility software will manage Furuno format waypoints so you do not need to write your own code. I used to have one of those VX2 units and used GPSU successfully to store, transfer, and edit. It is free software unless you need to manage more than 100 waypoints, in which case there is a small charge for the full version. It works very well. Do a search and you will find the website and can download the trial.
You can download and use it as a trial for free to make sure it does what you need, then buy a full copy and get the code to unlock it so you can use with more than 100 waypoints.
Another member sent me a PM and suggested it. This was software I had used years ago and had forgotten about. I found it very useful then. I called Carl and he had my records of when I originally purchased it in 1998 so I was able to get an upgrade for $25. :grin: Got my numbers downloaded and imported, good to go! :thumbsup: It is very versatile and will convert numbers to different formats for uploading into a different machine.
Worth a look!
