The simpliest way is to install the GPS tracker with OBDII interface in the diagnostic connector of the car. It takes 1 minute — and you will see the current car position and speed. Some models of OBDII-trackers can read extra information from the car electronic units: coolant and oil temperature, instant fuel consumption, rpm, throttle position and other parameters.
