Garmin 3600a Installation Instruction

QueGPS provides signal strength bars and a status 

field at the top of the screen so you can view the status 

of the GPS receiver. 

1.  Open QueGPS by tapping the status icon 

 at the bottom of the screen.

2.  Observe the message in the top of the window. 

  “Acquiring Satellites”—GPS is on and 

searching for satellite signals.

  “3D GPS Location”—a 3D location fix has 

been established.

  “3D Differential GPS Location”—WAAS 

satellite signals are being received and a 3D 

location fix is established.

  “2D Differential GPS Location”—only enough 

WAAS satellite signals are being received to 

determine a 2D location fix.

  “2D GPS Location”—enough satellite signals 

are being received to establish a 2D fix.

  “GPS is Off”—the antenna is closed.

While the receiver is gathering information, your 

location on the map may display as different from 

where you actually are located. Be patient; as soon as 

the receiver gathers enough satellite information, your 

proper location is displayed on the map.
Any time you have traveled more than 600 miles with 

the GPS receiver turned off, the receiver may take 

longer than normal to initialize and find your location.
The GPS receiver can lose satellite signals due to 

interference from such items as buildings, tunnels, 

and heavy tree cover. Monitoring the GPS status is 

recommended. 
If you do not want the GPS receiver on, keep the 

antenna closed, particularly when indoors.
