Night Mode (Switch); Manage Poi (Points Of Interest) - Uniden GNS8430 Owner's Manual

4.7.2.3 Night Mode (switch)

Turn on or off the night colours manually to override the automatic colour scheme
switching.
Note: Using this option turns off the Automatic Night Colours feature. You need to
re-enable it at the General settings screen (Page 54) to have the colours change
automatically again.

4.7.2.4 Manage POI (Points of Interest)

Here you can set all the parameters of POIs that you have created and the visibility
of the built-in POIs that come with the map.
Manage built-in POI visibility
The maps in Uniden Navigation come with a huge number of POIs. Displaying all of them
would make the maps too crowded (to see how POI items are shown on the map see
Page 24). In order to avoid that, you can decide which POI groups to show and which
ones to hide on the map. Uniden Navigation has a multi-level POI category system. You
can set the visibility of the top two levels. All levels below that will be shown or hidden
according to their respective category (i.e. you can set the visibility of Petrol
Stations in the Services category, but all brands listed under that will either be shown or
suppressed together).
