Garmin gpsmap 172 Manuale Utente

1.   Press the MENU key twice for the Main Menu. Press Up or Down on the ARROW KEYPAD until 

the ‘GPS’ tab is highlighted, then press the 

MENU key once.

2.   Using the ARROW KEYPAD, highlight ‘Initialize Position’ and press ENTER to initialize the 

receiver from the map. The Initialize Position Page appears, prompting you to select your approxi-
mate location with the map cursor.

3.  Use the ARROW KEYPAD to move the map cursor and point to your approximate location within 

200 miles. If you have difficulty identifying your position, press and release the IN key to see the 
next lower map scale.  

4.  Once you have determined your approximate location on the map, press the ENTER key.

This does not “calibrate” the unit in any way, but rather helps to speed up the initial 
satellite acquisition. If the unit displays “Ready (2D) or (3D )” during this process, it is 
not necessary to initialize the unit.

The GPS Information Page appears as the receiver begins acquiring satellites for your region and 

should acquire a fix within a few minutes. When viewing the ‘GPS’ tab on the Main Menu, a signal 
strength bar for each satellite in view appears on the bottom of the page, with the appropriate satellite 
number under each bar. The progress of satellite acquisition is shown in three stages:

•   No signal strength bars— the receiver is looking for the satellites indicated.
•  Hollow signal strength bars— the receiver has found the indicated satellite(s) and is collecting 

data.

•   Solid signal strength bars— the receiver has collected the necessary data and the satellite(s) are 

ready for use.

Once the receiver has collected information from at least three satellites, the top of the screen 

displays either “Ready (2D or 3D)”, and the GPSMAP 172/172C is ready for use.
