Acquiring GPS Satellite Signals
When you turn on the unit, the GPS receiver must collect satellite
data and establish the current location. When the unit acquires
satellite signals, the signal strength bars at the top of the Home
screen are green . When the unit loses satellite signals, the
green bars disappear and the position icon displays a ashing
question mark.

www.garmin.com/aboutGPS.

Simulator mode turns the GPS receiver off for use indoors or for
practice. The unit does not track satellites in simulator mode.
WARNING
