Getting Started Getting Started Acquiring GPS Satellite Signals When you turn on the chartplotter, the GPS receiver must collect satellite data and establish its current location. When the chartplotter acquires satellite signals, the signal strength bars at the top of the Home screen are green . When the chartplotter loses satellite signals, the green bars disappear and a flashing question mark appears on the boat icon on the Chart screen.
