Download the firmware and read the tutorial @ MT Best's GT31 section

Firmware versions downloaded from this website after V1.2B1405 (after 14 May 2009) provide SDOP data that is required for error-margin computations and Speed Records. Later versions include bug fixes and various User Interface improvements. Please read README file associated (and zipped) with a version to discover what changes were made in respect to previous versions.
I have succesfully updated the firmware today, still need to test it @ the water coming week.
hoe bevalt jou de nieuwe software???

Goede tip om die software van een update te voorzien!
