Help Me Change Como 2.0 display from km to miles

[Commish]

I just bought a Como 2.0 at a deep discount, and am very pleased with its performance. I've been unable, however, to change the display from km to miles. I followed the manual directions of long holding the set button twice, but never got to a screen where I could toggled between km and miles. Not a big deal, but any help appreciated.
