First -- yeah, I've been surprised when I shoved it in km/h. It's further off than that, and in mph still. I wish I was that dumb. :) Didn't /think/ I left the key on; it wasn't on when I loaded the thing to take it down to Arroyo Seco. Still -- definitely got the unit FUBAR, showing all the symptoms of the buggered head unit from the WR forum. I just haven't seen it reported anywhere else but there, and it's a pretty serious issue. I have one; I don't think it's do /that/ much of an adjustment. It is at least 3x off, and possibly more than that. Quite exciting, really. The new head unit is less than I feared, more than I hoped. I'll probably just stalk eBay for a bit and if that fails, get a new one. Boo.
