Backlight always on
You can choose to have the lights always on.
Use device settings
You can preserve the GNS8430/8435 device settings (previously set in the operating
system at Start/Settings/Backlight).
Smart powersave
You can also initiate this special feature of Uniden Navigation. When running on
battery Smart Powersave will light up the screen only when you press or tap a
button, or if Uniden Navigation has something to show you. After a few seconds the
light level decreases, and after another few seconds the backlight turns off. This
helps you achieve a longer battery life.
5.7.2.1 Brightness
5.7.3 Brightness
With this switch you can instruct Uniden Navigation to use the original settings of
the GNS8430/8435 device (previously set in the operating system at Start/Settings/
Backlight), or you can set the backlight level separately for both daylight and night
modes, thus enhancing the effect of the night colour scheme.
5.7.4 Smart Zoom
Smart zoom is a lot more than just a usual automatic zoom.
While navigating a route: when approaching a turn, it will zoom in and raise the
view angle to let you easily recognise your manoeuvre at the next junction. If the next
turn is at a distance, it will zoom out and lower the view angle to be flat in order to let
you see the road in front of you, or it can even switch to an Overview mode to let you
follow your position on the map.
While cruising: if there is no active route and you are just driving, Smart Zoom will
zoom in if you drive slowly and zoom out to the limit set here when you drive at high
speed.
These automatic features can be set up on this screen.
