When navigating using Nuvi 3490 it's not convenient to switch between the options displaying "Arrival Time, Distance, Time to Destination", etc., as it brings you to the menu screen where the right option should be selected & Save button needs to be pressed. That is quite distractive while driving, so it'd be more usable if pressing the button with current setting switched the current mode directly, i.e. "Arrival Time -> Distance -> Time to Destination" with immediate effect.
