    摘要: A method, a circuit arrangement and a navigation system are disclosed, whereby an extraction and transmission of signals running along a line bus (1, 2) are carried out without a separation of the bus cable being necessary. Furthermore, a sensor (4) is disclosed, which generates sensor signals repeating the line signals, whereby the output sensor signals are amplified by means of a signal processing (11) and transformed into a defined digital signal form (22). The filtered signals are then transmitted to a display device (14) or a further device by means of an additional bus either via a wireless or a line means. The invention further relates to a tapping device for the wireless tapping of CAN data from a CAN line by means of the electromagnetic field, without having to separate the CAN lines, comprising an upper pivoting form piece (32), which may be pressed by pivoting against a lower piece (35) by means of a pivot mechanism (41) for housing CAN cables and guide grooves (31) for housing the CAN cables (CAN1, CAN2), whereby in the closed position of the pivot mechanism, conductor loops are closed around the CAN cable which may be connected to signal processing electronics.
