	The satellite signal includes the time at which the signal was sent	If the complaint is still present: ↓
	The navigation processor Calculate the transmission time of the signal resulting from the satellite position and the transmission time of the GPS signal and can therefore determine the vehicle position (min. 3 satellites).	2 Perform test drive with new navigation CD version.
	If the GPS signal is falsified the transmitted time from the satellites is changed. A change of 10 ns corresponds to approx. 3 m position change	When the complaint is eliminated, use new navigation CD.
		If the complaint is still present: ↓ 3 Perform test drive with other vehicle and navigation system of other manufacturer.
		If the complaint does not occur during the test drive, a digitization error on the navigation CD is present: ↓ 4 Inform customers of facts and manufacturer of CD with report form If the correct report form from the manufacturer is not available, please contact corresponding service center (telephone number is given on label of navigation CD):
