Speedometer programming

[Pete Masterson]

I've had auto speedometers that were rather off ... a speedometer
shop was able to make a quick fix for not a lot of $$. You might look
for one that can handle a bus...

Based on those radar-speed signs, the speedo on my coach seems to be
reasonably accurate.

With 256 possible settings, you will be kept busy for some time to
come...
