Getting started Congratulations on your purchase of the system. Your system can guide you to the destination of your choice using signals from Global Positioning Satellites (GPS) orbiting the earth. There are 24 GPS satellites orbiting the earth. A GPS device can calculate your position on the earth if it can receive signals from at least three of these satellites. When it receives at least four signals, a GPS device can also calculate your altitude (height above sea level). To use the system for the first time you need to charge the battery, install the map loader onto your computer, and install map data onto the system. You can install the map loader while the battery is charging. Charging the battery To charge the battery, plug the power cable into the system and into a power outlet. Let the battery fully charge (approximately four hours). The battery charge indicator is red while the battery is charging, and turns amber when the battery is fully charged. Starting the system Once you have charged the battery, you are ready to start the system. - 2 -
