I have a Yager GT 200i and can never remember how to set the time after putting the battery back in after the winter. There are 2 buttons: top (Mode) and bottom (Adj). Pressing the top toggles between MPG and KPH, pressing the bottom toggles between ODO, Trip1, and Trip 2. Pressing both button appears to do the function for the top or bottom buttons. Hmm, maybe I am just not pressing them at the same time?!?
I set it once and seemed easy but escapes me now.
