    The trip computer on our 850 has started acting funny. The display in
    the dash shows numbers in the correct format, but they do not make any
    sense, including the odometer. The one exception is the air temperature
    reading. It seems to be correct. I don't know if the actual computing is
    done in the dash unit where the display is or somewhere else. Any guidance
    would be greatly appreciated for if it comes to replacing a part, I would
    sure like to figure out in advance just which one.
    Thanks Brad

    Not sure I can help with you specific problem, but I believe that the 850
    actually has at least three computers that all need to talk to each other
    for the instrument display to work. In addition to the one in the trip
    computer, there is one in the speedometer and one in the transmission. I
    would take it to an experienced mechanic who can test each of the units.
