I plunked my phone down in front of my camera and recorded the process of updating the software on the GBD-H2000. I only had to restart the app once and try to reconnect the watch once and in one shot I got the software updated.
Just don’t ask me what changed because to this point I have no idea what was updated. There was some indication that the GPS data was updated, but beyond that I have no clue. And yes, I did an internet search to see if anyone knew — even Reddit — but I turned up nothing.
Once before Casio pushed a big software update that brought the Trekking exercise to the GBD-H2000. That update was accompanied by documentation that outlined the other details of the software that was changing.
I found no such bulletin for this update.
So right now I thinking that I may reach out to my contact at Casio G-Shock and see if I can get the scoop on what was changed on this update.
Until then enjoy this video where you can vicariously update G-Shock software.
