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 flashing question mark.

Using Simulator Mode
Simulator mode turns the GPS receiver off for use indoors or for practice. The
unit does not track satellites in simulator mode.
 WArnIng
Do not try to navigate using simulator mode, because the GPS receiver is
turned off. Any satellite signal-strength bars shown are only simulations and do
not represent the strength of actual satellite signals.
To turn on Simulator mode:
1. From the Home screen, select Configure > System > Simulator.
2. Select Setup to set speed, track control, and position.
