Updating Mazda cx3 software

[Ma’bad]

I have discovered a software update online and am interested in updating my Mazda's software from version 74...200 to the latest version, 320.

it is possible to update your Mazda's software oneself? Or is it too risky?
does anyone know the cost of getting it updated at a dealer?

Go for it! (But you are advised to try and do it only while travelling under 80km/h.)
