Uniden GNS8365BT - Manual (Page 95)

You can choose to have the lights always on.
Use device settings
You can preserve the PNA device settings (previously set in the operating system at
Start/Settings/Backlight).
Smart powersave
You can also initiate this special feature of iGO. When running on battery Smart
Powersave will light up the screen only when you press or tap a button, or if iGO 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 iGO to use the original settings of the PNA 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.
