I'm a runner.
I need to have a field that every 1 km sound an alarm and for 10 seconds view a partial time of this km.
This function we can calling AutoLap. The program may ask the distance for setting to zero and then restart automatically the partial odometer and the time of the lap.
The fieldsmay be 3, one with the odometer, one with the time of the lap and another one for the average time of the lap.
Oviously if this function exist, i choose anoher 2 fields with the total odometer and total time.

thanks,
Checco.
