| Main unit, navigation |
The main unit of the navigation system is the DVD/navigation unit, located in the luggage compartment of the car. In addition to carrying out navigation calculations, it also contains a GPS receiver, a DVD player for the digital map and a vibration gyro to keep track of the direction of the car.
If the car is reversed, there is a connection between the reversing light switch and the navigation unit.
Vehicle speed is sent from TC-ABS, received by the navigation unit, and incorporated into the navigation calculation.
