"For greater flexibility, the SP8600 series GPS devices connect directly to the 12V socket of the vehicle (cigarette lighter). They are true "Plug and Play" devices - easy to switch from one vehicle to another in just seconds - that offer cost-effective and efficient monitoring. They feature a 3-axis accelerometer, a G-Force sensor, and a quad-band GSM technology modem that allows them to operate anywhere in the world. The SP8600 series is ideal for rental vehicles, young drivers, mileage monitoring, and fuel consumption validation."
