ok, so here's the scoop: One of the selectable screen options covers up the odometer display so you can't see it. Only trouble is I can't remember which one. Look at what's displayng at the bottom of the instrument screen and turn it off. Or just play with the settings till you uncover it. I spent 4 years struggling with this and then one day a mechanic during a warrranty claim just fixed it. It's clearly a bug in teh software.
