5.3.1 Master sound volume/switch
The loudness of The NVX225 Navigator is independent of your PND settings. When
you run The NVX225 Navigator, the position of this fader determines the device
volume level. When you exit the program, the device settings return.
The left part of this control works as a mute button. Tap to mute all The NVX225
Navigator sounds. This works in tandem with the Mute button (4.5.11) on the map
screens. Switching one of them will change the status of the other.
5.3.2 Voice guidance volume/switch
The switch on the left can turn on or mute The NVX225 Navigator'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 The NVX225 Navigator 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 short list of matches on the screen.
5.3.4 Dynamic Volume
When driving at high speed, the noise in the car may be too loud to clearly
understand the voice guidance messages and to perceive the key sounds. Using
Dynamic Volume you can instruct The NVX225 Navigator to increase the volume
when your 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.
