SCREEN LAYOUT (WINDOWS)
The GNS 430’s display is divided into three separate
‘windows’ (or screen areas). The left 1/4 of the display
provides a COM window (top two lines) and a VLOC
window (bottom two lines). The right 3/4 of the display
consists of a GPS window, which shows the various
navigation, waypoint information and settings ‘pages’.

Each unique screen of information is referred to as

CURSORS
There are two separate cursors: a tuning cursor and a

the standby COM or VLOC frequency. If desired, press
