Basic Mechanics
A special harness connects the navigation system to your vehicle’s electrical
system circuits. Connection locations vary depending on vehicle design. In
brief, however, this is how the navigation system is connected:
• Ignition ON provides power to wake up the navigation system.
• Battery circuit powers the navigation system’s computer when the ignition
is OFF. This minimal source of power is needed to store the vehicle’s last
location/position, similar to the way the time on your vehicle’s clock is
stored while the car is OFF.
• Ground connection completes electrical circuits.
• Vehicle speed sensor circuit provides information on how fast the vehicle is
traveling.
