Trip Statistics
The trip statistics calculator computes an odometer setting,
maximum ground speed and average ground speed value,
providing options to reset each computation individually or a
master reset to reset all.
The trip statistics will continue to compute each data field across
power cycles and until manually reset. The "Reset All" selection
will prompt a confirm dialog box that must be used to reset all.
