I think it just writes something to the SD card after 100 km (that's where the 62 miles comes from). I'll bet we can use the Mazda Toolbox, but since my Google finds indicate that the maps haven't been updated yet from our version, I'm just going to wait, although it would be good to make a backup file in case the card goes bad. I wouldn't want to use Mazda Toolbox and find out I should have waited for the Fiat Toolbox to come online.
