OBC activation issue

[Mark_T]

I used my Durametric to enable my OBC so that I would have the outside temp display. When the OBC enabled, my whole dash reverted to imperial measure. I was able to change it all (speedo, trip, time, odometer) back to metric using the clock knob, except the outside temp still displays in Farneheit. Anyone know how to make the outside temp show in Celsius? There does not seem to be a way to do it with the Durametric tool.
