Disclosed is a method and a circuit configuration as well as a navigation system are disclosed, wherein the extraction and transmission of signals running on a line bus (1, 2) is carried out without having to sever the bus cable. Furthermore, a sensor (4) is disclosed, which outputs sensor signals reproducing the line signals and wherein the output sensor signals are amplified by a signal processing unit (11) and transformed into a defined digital signal shape (22). The filtered signals are then transmitted to a display device (14) or another device via an additional bus in wireless manner or by way of a line. The invention further relates to a tapping device for the wireless tapping of CAN data from a CAN line by the electromagnetic field, without having to sever the CAN lines, having a pivotable top shaped part (32), which can be pressed against a bottom part (35) by way of a pivot mechanism (41) for the purpose of accommodating CAN cables, and guide grooves (31 for accommodating the CAN cables (CAN1, CAN2), with conductor loops, in the closed position of the pivot mechanism, being closed around the CAN cables which are connectable to a signal processing electronics.
