Transfer of Wapoints and Routes to GP39 via USB

[jfordyce]

Hello,

I recently bought a GP39 and would like to transfer routes and waypoints into it via a USB stick. The data will be downloaded to the stick from my TimeZero software which can export in TimeZero (2 formats), GPX, KML/KMZ and CSV. The GP39 manual shows samples of the format that it wants, but I don't know what it is. Can you help?

Thanks,
J.E. Fordyce

GP39 uses GPX format on the USB.

Thanks, Johnny, I will try the upload with GPX. Sorry for the delay in getting back, but I was bumped off the board by mistake. It has now been fixed.
Cheers,
J.E. Fordyce

hi Guys

I converted my old waypoints from my gp32 to the .gpx format as mentioned above but the upload fails. the waypoint file works perfectly on a tzt2 but the gp39 wont accept it. Have I missed something here?

Is the GP39 running the newest software?

hi Sparky

the unit has the latest software update.

The GPX files used by the GP39 have a slightly diffrent header than the normal format. Andren software (Seamarks) has the proper format (GP39 GPX) as an option. If you don't have that software, I would recommend send the normal GPX to Furuno Support and they can convert it into the GP39 format. Another options is a temp wiring between the older GPS and the GP39 and conduct a direct data transfer. Because you are jumping RS232 to RS422 it isn't something you want to keep connected but it will work for a quick transfer. You take only the sender of the RS232 and the ground over into the RS422 +/- for the one way transfer. If the connection needs to stay all the time, you would need to obtain the proper RS232 to RS422 converter.

Hi, I got a GP39 few weeks ago. I succeed to transfer my Waypoints from applications like OpenCPN, Boating Navionics, Avalon Offshore to the GP39.

The French Furuno supports, says that this USB functionality is dedicated to microcde update, or backup to get the waypoints on a spare GP39 after any damage.

The format describe by the official Furuno docmentation is far away from the new GPX one.

Yes the GP39 is using, with the latest release, a GPX format, based on XML . But this format is not compatible with other equipments or applications.
If you want to see the format, you have just to create one waypoint in your GP-39, then ask for backup to the USB stick. Put the USB stick in your computer and look at the file

1) The file name must be: GP39_WptRte.gpx
2) the xml structure inside this file must uses this keywords only!
<?xml version="1.0"?>
<gpx version="1.1" xmlns="http://www.topografix.com/GPX/1/1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<wpt lat="47.480830000" lon="-2.900148333">
<name> CHIMERE </name>
<extensions>
<GP39Symbol>1</GP39Symbol>
<FECColor>2</FECColor>
<GP39Comment>BOUEE CHIMERE</GP39Comment>
<GP39Flag>1</GP39Flag>
</extensions>
</wpt>
</gpx>

As you can see Furuno is using <extensions> for Symbol, color, Comment and flag
The usual keyword <desc> is not there and replaced by <GP39Comment>, because this comment must be 13 caracteres maximum.

Now if you compare to OpenCPN GPX structure, you will see other specifics extensions, they are not compatible

<?xml version="1.0"?>
<gpx version="1.1" creator="OpenCPN" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.topografix.com/GPX/1/1" xmlns:gpxx="http://www.garmin.com/xmlschemas/GpxExtensions/v3" xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd" xmlnspencpn="http://www.opencpn.org">

</extensions>
</wpt>

So ,you can do the work yourself a copy/past from OpenCPN format to GP39 Format using an XML editor like OXYGENE XML editor, or create a small application making the job, or use
GPS Utility http://www.gpsu.co.uk. In the last release the GP39 is included.

Version 5.36 included:
....
Upgrade to GPX export to deal with Furuno GP39 files
Upgrade to both import and export of Furuno GP39 files to deal with Comments, Colour and Symbols
...

This application is running under Windows operating system. I am an Apple user, so I decided to make the job by hand using Oxygen xml editor.
For 350 Waypoints it takes 6 hours, with some mistakes.

There is only one error message, and noway to get the line number of that mistake, but Oxygen is a good tool to see all waypoints and minimize the errors.

Hope this reply be useful for other GP-39 users.
