5.3 Sound settings
Settings on this page determine the way V7 Navigation sounds.
5.3.1 Master sound volume/switch
The loudness of V7 Navigation is independent of your V7 Portable Navigation
System settings. When you run V7 Navigation, 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 V7 Navigation
sounds.
This works in tandem with the Mute button (Page 30) 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 V7 Navigation'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 V7 Navigation 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 matching streets 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
