Garmin 190-00683-00 Manuale Utente

The advanced keypad system on the GSPMAP 378/478 is 

designed to allow you to select options and enter data quickly and 

conveniently. As you progress through this owner’s manual, you 

are directed to press a specific key or highlight a field on the screen. 

When you are directed to press a key, you should press and quickly 

release the key. If the key needs to be held down for a period of time 

to start a secondary function, the instructions will tell you to do so. 

When a field is selected on the screen, it is highlighted in yellow. 
The following terms are used throughout this manual:

•  Highlight—move the highlighted area on the screen up, 

down, left, or right with the ROCKER to select individual 

fields. Moving the highlight to a given location allows you to 

make a selection, begin data entry, or scroll through a list. 

•  Field—the location on a page where data or an option can 

be shown and entered. Select (highlight) a field using the 

ROCKER to begin entering data or selecting options.

•  On-screen button—use the ROCKER to highlight a button 

and press ENTER to select the button. 

•  Scroll bar—when viewing a list of items too long to appear 

on the screen, a scroll bar appears along the right side of 

the list. To scroll through a list, press up or down on the 

ROCKER.

•  Default—the factory setting saved in the unit’s memory. You 

can change the settings, and you can also revert to the factory 

(default) settings when you select Restore Defaults.
