I need unitronTruefit Software

Welcome to the forum @hayder33 your asking for different software, TrueFit is for Unitron and Oticon uses Genie2 , you’ll also need the correct programming device, what’s the exact model your using?

I have unitron truefit v.3.2 but does not update to newer version

Do you have the correct programming device, Noahlink wireless for the later “discover/Blu” models onwards,older use icube ll, otherwise you’ll be good to go.
