Darl,

I have not heard of a coach odometer reading more than the DDEC or Pro Driver. It is usually the other way around because the speedometers our vintage coaches had did not always count distance traveled. They would cease functioning for short periods and they eventually just stop registering miles.

But I think you might have a CC dash. Different animal I think.

The new Prevost replacement speedo that replaces the original uses an LCD mileage display, and it replaces the electro mechanical original.
