OpenStreetMap
I just thought I’d update my diary and give a shout for my trusty GT-31. Every few years I revive it and take it out for some data logging. This year I took it around the new Waterbeach development near Cambridge, UK. It worked perfectly. This is an amazing piece of kit.
One slight let-down was discovering that GPSBabel seems to have dropped support for the GT-31’s native SBP format. I thought that might be the end of my OSM career, but then luckily I found that I can still run the old NaviSys software on Windows 11. I can’t connect to the GT-31 over USB any more (why not?) but I can load the SBP file from the SD card and convert it to GPX. I can then drop the GPX file straight into OSM’s iD editor. Such great software!

Hi, Jeff.
I’m not familiar with this device, but have you checked you’ve got the latest firmware?

Thanks Chris. I looked into this but couldn’t get the firmware updater to talk to the device. Windows 11 doesn’t support the Prolific PL-2032 USB-to-serial chip in the GT-31. I’ve tried installing an older Windows driver but without success. I might try again later.

Reading this it suggests you can take out the SD card put that into USB card reader and get the date into you PC that way. If the Data is not compatible I think GPS Babel will convert formats for you.

That’s OK. Too much help is better than none!
