The Power/Volume knob controls unit power and radio volume (Nav
and Com). Push the knob in to turn the unit on. Pull the knob out to
turn the unit off. When in Com or Nav radio modes, turn the knob to
control audio volume.
The COM key activates control of the Com radio. The Com radio
window on the left side of the display will be outlined.
The VOR key activates control of the Nav radio. The Nav radio window on the left side of the display will be outlined.

The SUSP key toggles between automatic or suspended leg sequencing.
The Data Card ejector is located on the lower left corner of the unit.
Software and databases can be updated by replacing the data card. Never
remove or insert the data card when the unit is powered on. With the

carefully pull it the rest of the way out. Note the orientation of the card.
It will only go back in when turned in the right direction. Replace the
data card by carefully pressing it into the slot completely. Do not force
the card, if it doesn’t go in easily it probably isn’t turned the right way.

or complete data entry or as a Menu key to display the available Menu
items for the active function.
The Large and Small concentric knobs are used to edit and select information. Turn the Large knob to move the cursor. Turn the Small knob to

Powering Up the GNS 480
Starting Up
The GNS 480 performs internal checks and shows the status of the tests during
start up. The startup screen, owner name (if entered), testing, position, and
database information shows on the screen for several seconds and then shows
the first Map page.
Power Up
1. Push the PWR/VOL knob in to turn on power.
2. When the position display appears, you can press CHG to manually enter
your present position or just wait a few seconds for the GNS 480 to
establish your position. The full power up sequence takes 2-3 minutes.
3. The GNS 480 performs a number of tests at startup to ensure proper
operation. You may press SKIP to bypass the startup tests, however,
completing these tests is required for IFR flight. Observe the tests and
needle swings for proper operation.
Database Check
The GNS 480 verifies the integrity and
expiration date of the database. Up to
two database cycles are supported. The
GNS 480 will load the appropriate current database cycle and also let you know
if a database is not current (dates invalid
or corrupt) with a message in amber.
