Every now and then, the fabulous Garmin 705 will get screwed up while “Saving History” when plugging into the computer. What’s good is that the data isn’t lost. What’s bad is that it can take some hacking at the internal structure of the file to fix it up.
I’ve put together a quick script that you can run on the files to fix them up. It’s not perfect (it won’t fix the lap data, for example). But it saves the time to stitch the files together by hand. The script is attached, and the instructions to use it are below. Be warned – it’s a little geeky.
