3790LMT Voice Command Access to nuRoute Prompted Calculation Mode

 

On my 3790LMT I am able to set route calculation mode to Prompted which means when you click Go after selecting a destination, you are presented with an option to choose the fastest, shortest, or most fuel efficient route. How do you access this option via a Voice Command?

Also, if Prompted is set and a route is recalculated, e.g., a turn is missed, which algorithm is used?

No prompting for recalculations

The recalc uses the same selection that was used for the initial calculation.

OK, that's cool, but if you

OK, that's cool, but if you have Prompted selected and you use a Voice Command to pick a destination, what algorithm is used since in fact you are not prompted? Seems like a major oversight.
