5.3.2 Voice guidance volume/switch
The switch on the left can turn on or mute N.I.C.E 430's audible guidance. When
turned on, the slider on the right will adjust the loudness of voice prompts. In its
leftmost position the voice guidance is suppressed, in its rightmost position the
master volume applies.
5.3.3 Key sound volume/switch
The switch on the left can turn the key sounds on or off. Key sounds are audible
confirmations of either pressing hardware buttons or tapping the touch screen. When
key sounds are turned on, the slider on the right will adjust their loudness. In its
leftmost position the key sounds are suppressed, in its rightmost position they are
played at the master volume level.
Note: The sound effects of N.I.C.E 430 are context sensitive. They will be different if,
for example you open or close a window, or you enable or disable a setting. They will
even let you know if you have entered enough letters of a street name to have a

speed exceeds a certain minimum, and reach its highest volume (determined by the
Master volume slider in Sound settings) at the given maximum speed.
Tap the Dynamic Volume button to turn on the feature. This will also open the screen
where you can set the minimum and maximum speeds.
