Brief description, Navigation: Description

GPS (Global Positioning System), which is used by the navigation system, comprises a number of satellites that orbit the earth at an altitude of 20,200 km. Due to their comparative locations, at least four satellites are always accessible for the user on the ground. The various car systems are equipped with direction and speed sensors that are used together with GPS to calculate the car's position and navigation. Together, these make it easy for the customer to find a specific address.

In order for the system to function properly, the DVD must be inserted into the DVD player, the infotainment system must be switched on and NAV must be selected on the monitor with the control button on ICM3.
